DETAILED DESCRIPTION First Exemplary Embodiment

A device system as an information processing system according to a firstexemplary embodiment of the present invention will be described withreference to FIG. 1. FIG. 1 illustrates an example of the device systemaccording to the first exemplary embodiment.

The device system according to the first exemplary embodiment includes aterminal device 10, devices (for example, devices 12 and 14), and aserver 16 as an example of an external device. In the exampleillustrated in FIG. 1, the terminal device 10, the devices 12 and 14,and the server 16 have a function of communicating with each other via acommunication path N such as a network. Of course, the terminal device10, the devices 12 and 14, and the server 16 may communicate with otherdevices via different communication paths without using thecommunication path N. In the example illustrated in FIG. 1, two devices(devices 12 and 14) are included in the device system, but one device orthree or more devices may be included in the device system. Further,plural terminal devices 10 and plural servers 16 may be included in thedevice system. The server 16 may not be included in the device system.

The terminal device 10 is a device such as a personal computer (PC), atablet PC, a smartphone, a mobile phone, or the like, and has a functionof transmitting and receiving data to and from other devices. Theterminal device 10 may be a wearable terminal (for example, a wristwatch type terminal, a wristband type terminal, an eyeglass typeterminal, a finger ring type terminal, a contact lens type terminal, anintracorporeal implantable terminal, a hearable terminal, or the like).For example, the terminal device 10 functions as a user interface unit(UI unit) when using the device.

The devices 12 and 14 are devices having functions, and examples thereofinclude an image forming device having an image forming function, a PC,a tablet PC, a smartphone, a mobile phone, a robot (a humanoid robot, ananimal robot other than humanoid, etc.), a projector, a display device(a liquid crystal display or the like), a recording device, areproducing device, an image capturing device (a camera or the like), arefrigerator, a rice cooker, a microwave oven, a coffee maker, a vacuumcleaner, a washing machine, an air conditioner, a lighting device, aclock, a surveillance camera, an automobile, a bicycle, an aircraft (forexample, an unmanned aerial vehicle (a so-called drone)), a gamemachine, and various types of sensing devices (for example, atemperature sensor, a humidity sensor, a voltage sensor, a currentsensor, etc.). The devices 12 and 14 may be devices that output anoutput to a user (for example, an image forming device or a PC), or maybe devices that do not output an output to a user (for example, asensing device). Further, all of the devices in the plural devices thatexecute linkage functions described below may be devices that output anoutput to a user. Alternatively, some devices may be devices that outputan output to the user and other devices may be devices that do notoutput any output to the user. Alternatively, all of the devices may bedevices that do not output an output to the user. The concept of thedevices 12 and 14 may include all kinds of devices. For example, thedevices according to the present exemplary embodiment may also includean information device, a video device, an audio device, and otherdevices. In addition, the devices 12 and 14 have a function oftransmitting and receiving data to and from other devices.

The server 16 is a device that manages data, manages user information,and manages the devices 12 and 14. In addition, the server 16 has afunction of transmitting and receiving data to and from other devices.

In the terminal device 10, a conversation partner having a function ofmaking a conversation with the user is used. The conversation partnerhas a function of receiving a message of the user and analyzing themessage contents to create a reply such as an answer to the message andprovide the reply to the user. For example, the message of the user isperformed using character input, voice input, image input, or the like,and the reply such as an answer is performed using character output,voice output, image output, or the like. The conversation partner isimplemented by executing, for example, a program, and the program isinstalled in, for example, the terminal device 10. Of course, theprogram related to the conversation partner may be installed in anexternal device such as the server 16, and the function of theconversation partner may be provided to the terminal device 10 from theexternal device such as the server 16.

The conversation partner is configured with, for example, an automaticresponse artificial intelligence (AI), which is implemented by AI. Theautomatic response AI has a function of analyzing message contents of auser and providing a reply such as an answer to the message contents tothe user. An automatic response AI may be a chatbot (an automatedchatting program using artificial intelligence). An automatic responseAI may have a learning function based on artificial intelligence andhave an ability to make a determination close to that of a human by thelearning function. Further, neural network type deep learning may beused, or reinforcement learning may be used to partially reinforce thelearning field. In addition, genetic algorithms, cluster analysis,self-organizing maps, ensemble learning, and the like may be used. Ofcourse, other artificial intelligence techniques may be used.

With the automatic response AI, the user is notified of the functionsthat each device has, or notified of the linkage functions executableusing plural functions, while making a conversation with the automaticresponse AI. A process of specifying the functions that each device hasand the linkage functions may be performed by the terminal device 10 ormay be performed by an external device such as the server 16. In thefollowing description, the specifying process is performed by theterminal device 10.

Hereinafter, the configuration of the terminal device 10 will bedescribed in detail with reference to FIG. 2.

A communication unit 18 is a communication interface and has a functionof transmitting data to another device and a function of receiving datafrom another device. The communication unit 18 may be a communicationinterface having a wireless communication function or a communicationinterface having a wired communication function. For example, thecommunication unit 18 is compatible with one or plural types ofcommunication methods and may communicate with a communication partneraccording to a communication method suitable for the communicationpartner (that is, a communication method with which the communicationpartner is compatible). The communication method is, for example,infrared communication, visible light communication, Wi-Fi (registeredtrademark) communication, near-field wireless communication (forexample, near field communication (NFC), etc.), and the like. Examplesof the near-field wireless communication include Felica (registeredtrademark), Bluetooth (registered trademark), RFID (Radio FrequencyIdentifier), and the like. Of course, other types of wirelesscommunication may be used as near-field wireless communication. Forexample, the communication unit 18 may switch the communication methodor the frequency band depending on the communication partner, or switchthe communication method or the frequency band depending on thesurrounding environment.

A UI unit 20 is a user interface unit and includes a display unit and anoperation unit. The display unit is, for example, a display device suchas a liquid crystal display. The operation unit is an input device suchas a touch panel or a keyboard. Of course, it may be a user interfacethat serves as a display unit and an operation unit (for example, atouch-type display, a device for electronically displaying a keyboard orthe like on a display, etc.). Further, the UI unit 20 may include avoice collecting unit such as a microphone or a voice generating unitsuch as a speaker. In this case, information may be input to theterminal device 10 by a voice input, or information may be generated byvoice.

The display unit of the UI unit 20 displays thereon, for example, animage captured by the camera, a device image associated with a deviceidentified as a device to be used (for example, a device used alone or adevice to be linked), a function image associated with a function, andthe like. The device image associated with the device may be an image(still image or moving image) representing the device captured by thecamera, or may be an image schematically representing the device (forexample, an icon). For example, the schematically indicated image datamay be created by a control unit 26 of the terminal device 10, may bestored in advance in a storage unit 24 of the terminal device 10, may bestored in the server 16 and provided from the server 16 to the terminaldevice 10, or may be stored in another device and provided from theother device to the terminal device 10. The function image associatedwith a function is, for example, an image such as an icon representingthe function.

A camera 22 as an image capturing unit generates image data (forexample, still image data or moving image data) by capturing an objectto be captured. The image is displayed on, for example, a display unitof the UI unit 20. The image displayed on the display unit may beoperated by the user. Image data captured by an external camera may betransmitted to the terminal device 10 via a communication path, and theimage may be displayed on the display unit of the UI unit 20. Even inthis case, the image may be operated by the user.

A storage unit 24 is a storage device such as a hard disk or memory (forexample, SSD etc.). The storage unit 24 stores, for example, devicefunction management information, linkage function managementinformation, various data, various programs (for example, an operatingsystem (OS), a program for implementing an automatic response AI(software), various application programs (application software), etc.),information indicating the address of each device (device addressinformation), information indicating the address of the server 16(server address information), information on the identified device,information on the identified device to be linked, information onfunctions that the identified device has, information on the linkagefunctions, and the like. Of course, these may be stored in separatestorage devices or may be stored in one storage device. The program forimplementing the automatic response AI may be stored in an externaldevice such as the server 16. Thus, when the program itself is executedby the external device, the function of the automatic response AI may beprovided from the external device to the terminal device 10. In thiscase, the program for implementing the automatic response AI may not bestored in the storage unit 24.

Hereinafter, the device function management information and the linkagefunction management information will be described.

The device function management information is information for managingthe functions that respective devices have, and includes, for example,information indicating association between device identificationinformation for identifying a device (device identification information)and function information indicating the function of the device. Thedevice identification information includes, for example, a device ID, adevice name, information indicating the type of the device, the modelnumber of the device, information for managing the device (for example,asset management number, etc.), information indicating the locationwhere the device is installed (position information of the device), adevice image associated with the device, address information of thedevice, and the like. The device image is, for example, an externalappearance image representing the device. The external appearance imagemay be an image representing the outside of the device (for example, thecasing of the device), an image representing a state where the casing isopened such that the inside thereof is seen from the outside (forexample, the internal structure), or an image representing a state wherethe device is covered with a packaging sheet or the like. The deviceimage may be an image generated by capturing the device (such as animage representing the outside of the device or an image representingthe inside), or an image imitating the device (for example, an icon).The function information includes, for example, a function ID, afunction name, or the like. For example, when the device 12 is an imageforming device and the image forming device has a print function, a scanfunction, and a copy function, the device identification information ofthe image forming device has, as an example, function informationindicating the print function, function information indicating the scanfunction, and function information indicating the copy function, whichare associated with each other. The functions that each device has arespecified (identified) by referring to the device function managementinformation.

The device managed by the device function management information is, forexample, a device (for example, the device 12 or 14) included in thedevice system. Of course, devices not included in the device system maybe managed by the device function management information. For example,the terminal device 10 may acquire information on a new device notincluded in the device system (information including deviceidentification information and function information) and newly registerthe information in the device function management information. Theinformation on the device may be acquired, for example, by using theInternet or the like, or may be input by an administrator or the like.Further, the terminal device 10 may update the device functionmanagement information at any timing, regularly, or at a timingdesignated by an administrator or the like. Thus, in some cases,function information indicating a function that the device does not havebefore updating but the device has after updating may be registered inthe device function management information. Similarly, in some cases,function information indicating a function that the device has beforeupdating but the device does not have after updating may be deleted fromor registered as unusable information in the device function managementinformation. The information for updating may be acquired, for example,using the Internet or the like, or may be input by an administrator orthe like. Of course, the terminal device 10 itself may not performacquisition of information on the device and generation or update of thedevice function management information, and an external device such asthe server 16 may perform the acquisition of information on the deviceand the generation or update of the device function managementinformation. In this case, the device function management informationgenerated or updated by the external device is transmitted from theexternal device to the terminal device 10, and is stored in the storageunit 24.

The linkage function management information is information for managinglinkage functions executed by linking plural functions to each other.When plural functions are linked to each other, one or plural linkagefunctions are executed. For example, the linkage functions may befunctions executable by linking plural functions that a single devicehas (for example, the device 12) to each other, or functions executableby linking plural functions that plural devices (for example, thedevices 12 and 14) have to each other. Further, the terminal device 10issuing the operation instruction may also be used as a device to belinked, and the function that the terminal device 10 has may also beused as a part of the linkage functions.

The linkage function may be a function executed without using a deviceas hardware. For example, the linkage function may be a functionexecuted by linking plural software to each other. Of course, thelinkage function may be a function executed by linking the function thatthe device has as hardware and the function implemented by software toeach other.

The linkage function management information is information indicating,for example, association between a combination of function informationindicating each function used in the linkage function and linkagefunction information indicating the linkage function. The linkagefunction information includes, for example, a linkage function ID, alinkage function name, or the like. When a solo function is updated, thelinkage function management information is also updated along with theupdate. As a result, the linkage function by plural functions that areunable to be linked to each other before updating becomes usable afterupdating, and on the contrary to this, the linkage function that isusable before updating become unusable after updating. The linkagefunction information indicating the linkage function that becomes usableafter updating is registered in the linkage function managementinformation, and the linkage function information indicating the linkagefunction that became unusable after updating is deleted from orregistered as unusable information in the device function managementinformation. The update of the linkage function management informationmay be performed by the terminal device 10 or may be performed by anexternal device such as the server 16. When the update of the linkagefunction management information is executed by an external device, theupdated linkage function management information is transmitted from theexternal device to the terminal device 10, and is stored in the storageunit 24.

In the case of linking plural devices to each other, for example, thelinkage function management information is information for managing alinkage function that uses plural functions that plural devices have,and is information indicating association between the combination of thedevice identification information for identifying each device used forthe linkage function and the linkage function information. Further, in acase of linking a device that has plural output functions (a device thatoutputs an output to a user and has plural output functions) and asensing device that does not have an output function (a device that doesnot output any output to a user), the linkage function managementinformation may include information indicating a combination of specificsensing device with a specific output function of the plural outputfunctions. Therefore, the output function used in combination with aspecific sensing device is specified from among the plural outputfunctions. As described above, when the device function managementinformation is updated, the linkage function management information isalso updated along with the update. As a result, the linkage function byplural devices that are unable to be linked to each other beforeupdating becomes usable after updating, and on the contrary to this, thelinkage function that is usable before updating become unusable afterupdating.

The linkage function may be a function executable by linking pluralfunctions, which are different from each other, to each other, or bylinking the same functions to each other. The linkage function may be afunction that is unusable before the linkage. The function that isunusable before the linkage may be a function that is usable by usingthe same function among the functions that a device to be linked has orthat is usable by combining different functions. For example, when adevice having a print function (printer) and a device having a scanfunction (scanner) are linked to each other, a copy function isimplemented as a linkage function. That is, the copy function isimplemented by linking the print function and the scan function to eachother. In this case, the copy function as a linkage function and acombination of the print function and the scan function are associatedwith each other. In the linkage function management information, forexample, linkage function information indicating the copy function as alinkage function is associated with a combination of deviceidentification information for identifying a device having a printfunction and device identification information for identifying a devicehaving a scan function.

The concept of the linkage function may include a coalescing functionenabling a new function to be executed by linking plural functions orplural devices to each other. For example, an extended display functionmay be implemented as a coalescing function by combining pluraldisplays. As another example, a recording function may be implemented asa coalescing function by combining a television and a recorder. Therecording function may be a function of recording an image displayed onthe television. In addition, a capturing area extension function may beimplemented as a coalescing function by combining plural cameras. Theextension function is, for example, a function of capturing byconnecting the capturing areas of the respective cameras. In addition, atranslated call function (a function of translating a conversation via atelephone) may be implemented as a coalescing function by combining atelephone with a translator or translation software. As described above,the concept of the linkage function includes a function that may beimplemented by linking the same types of devices or functions to eachother and a function that may be implemented by linking different typesof devices or functions to each other.

A control unit 26 controls the operation of each unit of the terminaldevice 10. The control unit 26 controls communication, for example, bythe communication unit 18, and controls display of information on thedisplay unit of the UI unit 20. Further, the control unit 26 includes aposition information acquiring unit 28 and a specifying unit 30.

The position information acquiring unit 28 has a function of acquiringinformation (position information) indicating the positions of theterminal device 10 and each device (for example, each of the devices 12and 14) by using, for example, a global positioning system (GPS). Theposition information of the device includes device identificationinformation for identifying the device.

The specifying unit 30 has a function of specifying functions that adevice has or linkage functions executable using plural devices. Thespecifying unit 30 is implemented by, for example, the automaticresponse AI. Of course, the specifying unit 30 may be implemented byanother program or the like, instead of being implemented by theautomatic response AI.

The specifying unit 30 receives device identification information foridentifying a device designated by a user and specifies functioninformation indicating a function associated with the deviceidentification information in the device function management informationstored in the storage unit 24. Therefore, the function that the devicehas is specified (identified).

Further, the specifying unit 30 may receive device identificationinformation included in the position information acquired by theposition information acquiring unit 28 and specify function informationindicating the function associated with the device identificationinformation in the device function management information. For example,the specifying unit 30 specifies the positional relationship between theterminal device 10 (the user) and the device based on the positioninformation of the terminal device 10 and the position information ofthe device. When the positional relationship falls within a predefinedspecific positional relationship, the specifying unit 30 may specify thefunction that the device has based on the device identificationinformation included in the position information of the device and thedevice function management information. For example, when the terminaldevice 10 exists in a predetermined area including the device, thespecifying unit 30 specifies the function that the device has.

The control unit 26 controls notification (guidance) of information onthe function specified by the specifying unit 30 (for example, functioninformation, function explanation information, and the like). As thenotification, the control unit 26 may cause the display unit of the UIunit 20 to display the information on the function, or may use a speakeror the like to generate information on the function as voiceinformation. Further, the control unit 26 may control the execution ofthe function. Further, the designation of the device by the user may beperformed on the screen of the display unit of the UI unit 20, or may beperformed by voice. For example, when an image associated with a deviceis displayed on the screen of the UI unit 20, the user may designate thedevice by designating the image on the screen. As another example, theuser may designate the device by voice, regardless of whether or not animage associated with the device is displayed on the screen of the UIunit 20. For example, when the user issues a device name by voice, thevoice is collected by a voice collecting unit such as a microphone, andvoice information indicating the device name is input to the terminaldevice 10. The specifying unit 30 determines that the device having thedevice name is designated by the user and specifies the function. Inthis manner, the device designating operation and the functionnotification may be performed by on-screen display or by voice. Theon-screen display and the voice may be combined. For example, the devicemay be designated by the user's designation of an image associated withthe device on the screen, and information indicating the function may bedisplayed on the screen. As another example, the device may bedesignated by the user's designation of an image associated with thedevice on the screen, and information indicating a function may begenerated by voice. As still another example, the device may bedesignated by inputting the device name to the terminal device 10 asvoice information, and information indicating a function may bedisplayed on the screen. As yet another example, the device may bedesignated by inputting the device name to the terminal device 10 asvoice information, and information indicating a function may begenerated by voice.

The process of specifying the function may be performed by the server16. In this case, the device identification information is transmittedfrom the terminal device 10 to the server 16, and the specifying unit 30provided in the server 16 specifies function information indicating afunction associated with the device identification information. In thecase where the specifying process is performed by the server 16, thedevice function management information is stored in the server 16. Theinformation on the function may be transmitted from the server 16 to theterminal device 10 and displayed on the display unit of the UI unit 20or generated as voice information.

Further, the specifying unit 30 receives the device identificationinformation for identifying respective devices to be linked andspecifies linkage function information indicating a linkage functionassociated with a combination of respective device identificationinformation in the linkage function management information stored in thestorage unit 24. Therefore, the linkage function executable by linkingthe functions that the respective devices to be linked have is specified(identified). The control unit 26 controls notification (guidance) ofinformation on the specified linkage function (for example, linkagefunction information, linkage function explanation information, and thelike). The control unit 26 may cause the display unit of the UI unit 20to display the information on the linkage function, or may generateinformation on the linkage function as voice information. Similarly, thedesignation of each device to be linked may be performed on the screenor by voice.

The specifying unit 30 may receive the device identification informationincluded in the position information of each device and specify thelinkage function based on each device identification information and thelinkage function management information.

The process of specifying the linkage function may be performed by theserver 16. In this case, plural pieces of device identificationinformation are transmitted from the terminal device 10 to the server16, and the specifying unit 30 provided in the server 16 specifieslinkage function information indicating linkage functions associatedwith the plural pieces of device identification information. In the casewhere the specifying process is performed by the server 16, the linkagefunction management information is stored in the server 16. Theinformation on the linkage functions may be transmitted from the server16 to the terminal device 10 and displayed on the display unit of the UIunit 20 or generated as voice information.

For example, when one device is designated, a function that the devicehas is specified, and when plural devices are designated, a linkagefunction executable using the plural devices is specified.

Further, the specifying unit 30 may receive function informationindicating respective functions used for the linkage function andspecify the linkage function information indicating the linkage functionassociated with a combination of respective function information in thelinkage function management information. Therefore, the linkage functionexecutable by linking the respective functions to be linked is specified(identified). The specifying process is also performed by the server 16,and the process result may be displayed on the display unit of the UIunit 20 or may be generated as voice information.

For example, the device is designated as the user transmits the deviceinformation to the automatic response AI. When the user transmitsinformation of plural devices to the automatic response AI, thespecifying unit 30 identifies the plural devices as devices to be linkedand specifies the linkage functions executable using the plural devices.Further, when the user transmits information of one device to theautomatic response AI, the specifying unit 30 identifies the device andspecifies the function that the device has. The information of thedevice is device identification information for identifying the device,and examples thereof include a device image associated with the device,character information or voice information indicating the deviceidentification information, and the like. For example, when a usertransmits a device image associated with a device to an automaticresponse AI, or when a user inputs a character string indicating deviceidentification information of the device into the terminal device 10 andgives it to the automatic response AI, or when a user gives the deviceidentification information of the device to the automatic response AI byvoice, the specifying unit 30 (the specifying unit 30 implemented by theautomatic response AI) identifies the device.

Functions usable by a user (a solo function or linkage function that thedevice has) may be managed for each user. The management may beperformed by the terminal device 10 or may be performed by an externaldevice such as the server 16. The functions usable by a user include,for example, a function provided to the user for free, a functionprovided to the user for a charge and purchased by the user, and thelike. Usable function information indicating functions usable by theuser (for example, function purchase history information) may be createdand managed for each user. When the management of the usable functionsis performed by the terminal device 10, the usable function informationis stored in the storage unit 24. When the management is performed by anexternal device such as the server 16, the usable function informationis stored in the external device. Of course, there are also functionsthat may be used for free, additional update functions, and functionsthat are specifically managed by an administrator. Therefore, theusability of the function may not be determined based on the presence orabsence of purchase. A process of purchasing the functions is performed,for example, by an external device such as the server 16.

The usable function management information is information for managingthe functions usable by respective users, and is, for example,information indicating association between user identificationinformation for identifying a user and function information indicatingthe function usable by the user (which may include linkage functioninformation). As described above, the function usable by the user is,for example, a function provided to the user for free, a functionpurchased by the user, and the like, which may be a single function or alinkage function. The user identification information is, for example,user account information such as user ID and name. The functions usableby each user are specified (identified) by referring to the usablefunction management information. The usable function managementinformation may be updated, for example, each time when a function isprovided to the user (for example, each time when a function is providedto the user for free or for a charge).

When the functions usable by a user are managed, the specifying unit 30may receive user identification information for identifying the user andspecify function information indicating each function associated withthe user identification information in the usable function managementinformation (for example, the information stored in the terminal device10 or server 16). As a result, functions usable by the user arespecified (identified). The control unit 26 may cause the display unitof the UI unit 20 to display the information on the specified function,or may generate the information as voice information. For example, thespecifying unit 30 receives the device identification information andthe user identification information, specifies function informationindicating a function associated with the device identificationinformation in the device function management information, and furtherspecifies function information indicating a function associated with theuser identification information in the usable function managementinformation. As a result, the function that the device specified by thedevice identification information has and is usable by the useridentified by the user identification information, is specified.

The functions usable by the user may be specified by an external devicesuch as the server 16. In this case, the user identification informationis transmitted from the terminal device 10 to the server 16, and thespecifying unit 30 provided in the server 16 specifies functioninformation indicating a function associated with the useridentification information. In the case where the specifying process isperformed by the server 16, the usable function information is stored inthe server 16. Information on each function usable by the user may betransmitted from the server 16 to the terminal device 10 and displayedon the display unit of the UI unit 20 or generated as voice information.

Hereinafter, the configuration of the device 12 will be described indetail with reference to FIG. 3. As an example, it is assumed that thedevice 12 is an image forming device. Hereinafter, the device 12 may bereferred to as the image forming device 12 in some cases. FIG. 3illustrates the configuration of the image forming device 12.

A communication unit 32 is a communication interface and has a functionof transmitting data to another device and a function of receiving datafrom another device. The communication unit 32 may be a communicationinterface having a wireless communication function or a communicationinterface having a wired communication function. For example, thecommunication unit 32 is compatible with one or plural types ofcommunication methods and may communicate with a communication partneraccording to a communication method suitable for the communicationpartner (that is, a communication method with which the communicationpartner is compatible). The communication method is, for example,infrared communication, visible light communication, Wi-Ficommunication, near-field wireless communication, and the like. Forexample, the communication unit 32 may switch the communication methodor the frequency band depending on the communication partner, or switchthe communication method or the frequency band depending on thesurrounding environment.

An image forming unit 34 has an image forming function. Specifically,the image forming unit 34 has at least one function among a scanfunction, a print function, a copy function, or a facsimile function.When the scan function is executed, a document is read and scan data(image data) is generated. When the print function is executed, theimage is printed on a recording medium such as paper. When the copyfunction is executed, the document is read and printed on the recordingmedium. When the facsimile function is executed, the image data istransmitted by facsimile transmission or facsimile reception. Inaddition, a linkage function using plural functions may be executed. Forexample, a scan transfer function which is a combination of a scanfunction and a transmission function (transfer function) may beexecuted. When the scan transfer function is executed, a document isread to generate scan data (image data), and the scan data istransmitted to a transmission destination (for example, an externaldevice such as the terminal device 10). Of course, this linkage functionis merely an example, and another linkage function may be executed.

A storage unit 36 is a storage device such as a hard disk or memory (forexample, SSD etc.). The storage unit 36 stores, for example, informationindicating an instruction of image formation (for example, jobinformation), image data to be printed, scan data generated by executingthe scan function, device address information indicating addresses ofother devices, information indicating an address of the terminal device10 (terminal address information), server address information of theserver 16, various control data, various programs, and the like. Ofcourse, these may be stored in separate storage devices or may be storedin one storage device.

A UI unit 38 is a user interface unit and includes a display unit and anoperation unit. The display unit is, for example, a display device suchas a liquid crystal display. The operation unit is an input device suchas a touch panel or a keyboard. Of course, it may be a user interfacethat serves as a display unit and an operation unit (for example, atouch-type display, a device for electronically displaying a keyboard orthe like on a display, etc.). The image forming device 12 may not havethe UI unit 38, or may have a hardware user interface unit (hardware UIunit) as hardware without a display unit. The hardware UI unit is, forexample, a hardware key (for example, numeric keypad) specialized fornumeric input, a hardware key (for example, direction instruction key)specialized for direction instruction, and the like.

A control unit 40 controls the operation of each unit of the imageforming device 12.

Hereinafter, the configuration of the server 16 will be described indetail with reference to FIG. 4. FIG. 4 illustrates the configuration ofthe server 16.

A communication unit 42 is a communication interface and has a functionof transmitting data to another device and a function of receiving datafrom another device. The communication unit 42 may be a communicationinterface having a wireless communication function or a communicationinterface having a wired communication function.

A storage unit 44 is a storage device such as a hard disk or memory (forexample, SSD etc.). The storage unit 44 stores, for example, variousdata, various programs, terminal address information of the terminaldevice 10, device address information of each device, server addressinformation of the server 16, and the like. Of course, these may bestored in separate storage devices or may be stored in one storagedevice.

When the functions that the respective devices have and the linkagefunctions are managed by the server 16, the above-described devicefunction management information and linkage function managementinformation may be stored in the storage unit 44, and then, the devicefunction management information and the linkage function managementinformation may be updated in the server 16. In this case, when aprocess of specifying the function is performed by the terminal device10, the device function management information and the linkage functionmanagement information (the updated information when the information isupdated) are transmitted from the server 16 to the terminal device 10.The transmission may be performed regularly or at a designated timing.Thus, the information stored in the terminal device 10 is updated. Ofcourse, the specifying unit 30 of the terminal device 10 may specifyfunctions that the device has or linkage functions by referring to thedevice function management information and the linkage functionmanagement information stored in the server 16. Further, the process ofspecifying the function may be executed by the server 16.

The control unit 46 controls the operation of each unit of the server16. The control unit 46 controls communication, for example, by thecommunication unit 42.

The control unit 46 may execute a function purchase and manage thehistory of the purchase. For example, when a paid function is purchasedby a user, the control unit 46 may apply a charging process to the user.

Further, the control unit 46 may execute functions related to imageprocessing such as, for example, a character recognition function, atranslation function, an image processing function, and an image formingfunction. Of course, the control unit 46 may execute functions relatedto any process other than the image processing. By executing thecharacter recognition function, characters in the image are recognizedand character data indicating the character is generated. By executingthe translation function, the characters in the image are translatedinto characters represented in a specific language, and character dataindicating the translated characters is generated. By executing theimage processing function, the image is processed. The control unit 46may receive, for example, scan data generated by executing the scanfunction from the image forming device 12 and execute functions relatedto the image processing such as the character recognition function, thetranslation function, the image processing function, and the like, withrespect to the scan data. The control unit 46 may receive image datafrom the terminal device 10 and execute the respective functions on theimage data. The character data and image data generated by the controlunit 46 are transmitted, for example, from the server 16 to the terminaldevice 10. The server 16 is used as an external device, and the linkagefunction may be a function of using functions that plural devicesincluding the server 16 have.

As described above, the device function management information may bestored in the storage unit 44 of the server 16. In this case, the devicefunction management information may not be stored in the storage unit 24of the terminal device 10. Similarly, the linkage function managementinformation may not be stored in the storage unit 44 of the server 16.In this case, the linkage function management information may not bestored in the storage unit 24 of the terminal device 10. The controlunit 46 of the server 16 may have the specifying unit 30 describedabove, and may identify the device based on the device identificationinformation and specify the function that the device has or may specifya linkage function executable using plural functions. In this case, theterminal device 10 may not have the specifying unit 30.

When usable function management information is created, the usablefunction management information may be stored in the storage unit 44 ofthe server 16. In this case, the usable function management informationmay not be stored in the storage unit 24 of the terminal device 10. Thecontrol unit 26 of the terminal device 10 may manage the history of thepurchase of functions by a user. In this case, the control unit 46 ofthe server 16 may not have the management function thereof.

As still another example, the device function management information andthe linkage function management information may be stored in the devicessuch as the devices 12 and 14, or the devices such as the devices 12 and14 may have the specifying unit 30. That is, the process by thespecifying unit 30 may be performed in the terminal device 10, thedevices such as the devices 12 and 14, the server 16, or another device.

Hereinafter, the device system according to the first exemplaryembodiment will be described in more detail.

The device function management information will be described in detailwith reference to FIG. 5. FIG. 5 illustrates an exemplary devicefunction management table as the device function management information.In the device function management table, as an example, the device ID,the information indicating the device name (for example, the type of thedevice), the information indicating the function that the device has(function information), and the image ID are associated with each other.The device ID and the device name correspond to an example of the deviceidentification information. The image ID is an example of imageidentification information for identifying a device image associatedwith the device. The device function management table may not includethe image ID. For example, a device whose device ID is “B” is amultifunction device (an image forming device having plural imageforming functions), and has functions such as a print function and ascan function. The device is associated with an image ID for identifyinga device image associated with the device. The data of the device imageassociated with the device may be stored in, for example, the terminaldevice 10, the server 16, or another device.

For example, the position information acquired by the positioninformation acquiring unit 28 includes information indicating the deviceID and device name as device identification information. The specifyingunit 30 of the terminal device 10 specifies the device name, thefunction, and the image ID associated with the device ID by referring tothe device function management table. Therefore, the device to be usedis identified. Information indicating the device name or the deviceimage may be displayed on the display unit of the UI unit 20. Of course,the image itself captured by the camera 22 may be displayed on thedisplay unit of the UI unit 20. Further, when the device imageassociated with the device (for example, an image captured by the camera22 or an image schematically representing the device) is designated bythe user in the UI unit 20, information on the function that the devicehas (for example, function information, function explanationinformation, etc.) may be displayed on the display unit of the UI unit20.

Hereinafter, the linkage function management information will bedescribed in detail with reference to FIG. 6. FIG. 6 illustrates anexemplary linkage function management table as the linkage functionmanagement information. In the linkage function management table, as anexample, a combination of the device IDs, the information indicating thenames of the devices to be linked (for example, the types of thedevices), and the information indicating the linkage functions of thedevices (linkage function information) are associated with each other.For example, the device whose device ID is “A” is a PC (personalcomputer), and the device whose device ID is “B” is a multifunctiondevice. When the PC (A) and the multifunction device (B) are linked toeach other, for example, “scan transfer function” and “print function”are implemented as linkage functions. The “scan transfer function” is afunction of transferring image data generated by scanning by themultifunction device (B) to the PC (A). The “print function” is afunction of transmitting data (for example, image data and documentdata) saved in the PC (A) to the multifunction device (B) and printingit with the multifunction device (B). A linkage function executableusing three or more devices may be specified. In this case, acombination of three or more devices and a linkage function areassociated with each other, and the association is registered in thelinkage function management table.

Hereinafter, the operation of the terminal device 10 will be describedin detail with specific examples.

A positional relationship between the device and the user (the terminaldevice 10 that the user has) will be described with reference to FIG. 7.FIG. 7 illustrates the positional relationship. An area is defined foreach device. For example, the multifunction device (B) as a device 48has an area 50 having a predetermined size. The area 50 may be an areahaving a circular shape around an installation position of themultifunction device (B), an area having a rectangular shape, or an areahaving any shape. Further, the multifunction device (B) may not beinstalled at the center of the area 50. Areas for other devices are alsodetermined in the same manner as that of the multifunction device (B).The areas for respective devices may have the same size and the sameshape as each other, or may have different sizes and different shapesfrom each other. A user 52 is a user who exists in the area 50, and auser 54 is a user who exists outside the area 50. For example,information indicating an area of each device is stored in the storageunit 24 of the terminal device 10. Of course, the information indicatingthe area of each device may be stored in an external device such as theserver 16 or may be stored in the device. The position information ofthe device may also include information indicating the area of thedevice.

The specifying unit 30 identifies the position of the user (the terminaldevice 10) based on the position information of the terminal device 10acquired by the position information acquiring unit 28. Similarly, thespecifying unit 30 identifies the position of the multifunction device(B) based on the position information of the multifunction device (B)acquired by the position information acquiring unit 28. Further, thespecifying unit 30 identifies the area 50 of the multifunction device(B) based on the information indicating the area 50 of the multifunctiondevice (B). The information indicating the area 50 may be included inthe position information of the multifunction device (B), may be storedin the storage unit 24 of the terminal device 10, or may be stored in anexternal device such as the server 16.

The specifying unit 30 may calculate the distance between themultifunction device (B) and the user based on the position informationof the multifunction device (B) and the position information of the user(the terminal device 10), and determine the positional relationshipbetween the multifunction device (B) and the user based on the distance.For example, when the distance is equal to or less than a thresholdvalue, the specifying unit 30 determines that the user exists in thearea 50 of the multifunction device (B). When the distance exceeds thethreshold value, the specifying unit 30 determines that the user existsoutside the area 50 of the multifunction device (B). The same applies toother devices.

Hereinafter, a screen displayed on the terminal device 10 will bedescribed with reference to FIG. 8. FIG. 8 illustrates an example of thescreen displayed on the terminal device 10. The control unit 26 of theterminal device 10 causes the display unit of the UI unit 20 to displaya screen 56 and causes the screen 56 to display various kinds ofinformation. The screen 56 is an interface (conversation responsescreen) for the user to make a conversation with the automatic responseAI. The screen 56 displays thereon information (for example, a characterstring or an image) input by the user to the terminal device 10 andinformation indicating a message content of the automatic response AI(for example, a character string or an image). The conversation betweenthe user and the automatic response AI may be a conversation in aso-called chat format (that is, a conversation in a real-time format, inother words, a conversation in which the user and the automatic responseAI make messages). For example, a program for making a conversation withthe automatic response AI (for example, a chatting program) is executed,and the screen 56 for the conversation (conversation response screen) isdisplayed on the display unit of the UI unit 20.

The screen 56 is provided with a display area for each conversationparticipant is provided, and a message content of each conversationparticipant may be displayed in his/her own display area. For example,the display area 56 a is an area where the message contents of theautomatic response AI are displayed, and a display area 56 b is an areawhere the message contents of the user (the information input by theuser to the terminal device 10) are displayed. In the exampleillustrated in FIG. 8, the display area 56 a for the automatic responseAI is provided on the left side toward the screen 56, and the displayarea 56 b for the user is provided on the right side. Of course, thisdisplay example is merely an example, and the arrangement relationshipof the display areas may be reversed, the display areas may be providedin the vertical direction, or all or some of the display areas mayoverlap each other. The latest message content may be displayed in aspecific area (for example, the central area) on the screen 56, and thepast message contents may be displayed around that area. Further, therespective display areas may have the same size as each other, may havedifferent sizes from each other, or may be enlarged or reduced dependingon an amount of the content of a single message or the number of timesof messages. The setting and size of the display area are controlled bythe control unit 26.

In an example illustrated in FIG. 8, only one user and one automaticresponse AI are present in the conversation, but plural users and pluralautomatic response Ms may participate in the conversation. In this case,a display area for each conversation participant may be provided on thescreen 56. For example, when two users and one automatic response AIparticipate in a conversation, three display areas are provided on thescreen 56, and the message content of each conversation participant isdisplayed in its own display area. For example, when plural users make aconversation with each other via the screen 56 by communicating withplural terminal devices 10, the message contents of the plural users aredisplayed on the screen 56. The same applies to a case where pluralautomatic response AIs participate in a conversation. Plural automaticresponse AI programs may be installed in the same terminal device 10,and the plural automatic response AIs may be stored in the same terminaldevice 10. Alternatively, a program related to each of the pluralautomatic response Ms may be installed in a separate terminal device 10,and each automatic response AI may be stored in a separate terminaldevice 10. For example, the screen 56 displays the message contents ofthe automatic response AI stored in the terminal device 10 as its owndevice, and the message contents of the automatic response AI stored inanother terminal device 10. The automatic response AI stored in anotherterminal device 10 participates in the conversation, for example, via acommunication path N.

When the chatting program is activated, the control unit 26 of theterminal device 10 causes the display unit of the UI unit 20 to displaythe screen 56. An image 58 associated with the automatic response AI isdisplayed on the display area 56 a for the automatic response AI, and animage 60 associated with the user is displayed on the display area 56 bfor the user. The image 58 is an image for identifying the automaticresponse AI, and the image 60 is an image for identifying the user. Acharacter string indicating the automatic response AI (a characterstring for identifying the automatic response AI) may be displayed inplace of the image 58 or along with the image 58. Similarly, a characterstring indicating the user (a character string for identifying the user,such as a name, a user ID, a handle name, a nickname, etc.) may bedisplayed in place of the image 60 or along with the image 60. Theautomatic response AI is an automatic response AI that does not dependon the device, and may be a general-purpose automatic response AI.

Thereafter, a conversation is made between the user and the automaticresponse AI. In the conversation, the message contents of the user maybe input to the terminal device 10 as the user operates the UI unit 20to input information such as a character string or an image, or may beinput by voice. The message contents of the user may be displayed on thescreen 56 as information such as a character string or an image, or maynot be displayed. Similarly, the message contents of the automaticresponse AI may be displayed on the screen 56 as information such as acharacter string or an image, may not be displayed, or may be generatedas voice while being displayed. In the following description, as anexample, the message contents of each conversation participant isdisplayed on the screen 56. However, the message contents may begenerated by voice.

When the conversation progresses on the screen 56, the screen 56scrolls, so that the past message contents which are unable to bedisplayed on the screen 56 disappears from the screen 56, and the latestmessage contents and the immediate message contents are displayed on thescreen 56.

When the chatting program is activated, the automatic response AI firstissues a common question (a question asking about the user's request)such as “How can I help you?” and a character string indicating thequestion as a message content 62 of the automatic response AI isdisplayed in the display area 56 a. Of course, the message content ofthe automatic response AI may be generated by voice in place of thecharacter string or along with the character string. Since the messagecontent 62 is a message content of the automatic response AI, thecontrol unit 26 displays the message content 62 in the display area 56 aas a message content associated with the image 58 of the automaticresponse AI. The same applies to the following conversation.

The position information acquiring unit 28 acquires position informationof the terminal device 10 and position information of each device. Theposition information acquiring unit 28 may acquire the positioninformation at any time, may acquire the position information at apredetermined timing, may acquire the position information periodically,or may acquire the position information at a timing designated by theuser. The specifying unit 30 specifies the positional relationshipbetween the terminal device 10 (user) and each device based on theposition information of the terminal device 10 and the positioninformation of each device obtained by the position informationacquiring unit 28.

For example, as illustrated in FIG. 7, it is assumed that the user (theterminal device 10) exists in the area 50 of the multifunction device(B) (see the user 52). In this case, the specifying unit 30 determinesthat the user (the terminal device 10) exists in the area 50 of themultifunction device (B) based on the position information of theterminal device 10 and the position information of the multifunctiondevice (B). When the distance between the terminal device 10 and themultifunction device (B) is equal to or less than the threshold value,the specifying unit 30 may determine that the user (the terminal device10) exists in the area 50 of the multifunction device (B).

When the user (the terminal device 10) exists in the area 50 of themultifunction device (B), the specifying unit 30 identifies themultifunction device (B) as a device to be used and specifies a functionassociated with the device identification information included in theposition information of the multifunction device (B), for example, inthe device function management table illustrated in FIG. 5. Therefore,the function that the multifunction device (B) has is identified.

Further, when the user (the terminal device 10) exists in an area of adevice, the control unit 26 switches the display of the conversationpartner (for example, an image associated with the conversation partneror a character string indicating the conversation partner) from thedisplay of the general-purpose automatic response AI (for example, animage 58 associated with the general-purpose automatic response AI or acharacter string indicating the general-purpose automatic response AI)to the display of the device (for example, an image associated with thedevice or a character string indicating the device).

When the user exists in the area 50 of the multifunction device (B), thecontrol unit 26 displays the device image 66 associated with themultifunction device (B) in the display area 56 a as an image associatedwith the conversation partner, in place of the image 58 associated withthe automatic response AI. The device image 66 may be an image generatedby capturing the multifunction device (B) (for example, an externalappearance image of the multifunction device (B)), or may be an imageimitating the multifunction device (B) (for example, an icon). Ofcourse, the control unit 26 may display a character string indicatingthe multifunction device (B) in the display area 56 a as informationindicating the conversation partner, in place of the device image 66 oralong with the device image 66.

Further, the control unit 26 displays a message content 68 such as“Which function do you want to use?” in the display area 56 a as amessage content of the multifunction device (B). The message content 68itself is a message content created by the general-purpose automaticresponse AI. The control unit 26 displays the message content 68 in thedisplay area 56 a as a message content associated with the device image66 of the multifunction device (B), in order to act as if themultifunction device (B) makes the message content 68. The control unit26 may display a list of the functions that the multifunction device (B)specified by the specifying unit 30 has, in the display area 56 a as amessage content of the multifunction device (B). Since the multifunctiondevice (B) is a device having an image forming function such as a printfunction or a copy function, the control unit 26 may display a characterstring or an image indicating a list of the image forming functions inthe display area 56 a as a message content of the multifunction device(B).

Further, when the user requests use of a device by making a message suchas “I want to use the multifunction device (B)”, a character stringindicating the request may be displayed as a message content 64 of theuser in the display area 56 b. The user may input information indicatingthe message content to the terminal device 10 by operating the screen 56to input a character string, or may input information indicating themessage content to the terminal device 10 by voice. Since the messagecontent is a message content of the user, the control unit 26 displaysthe message content 64 in the display area 56 b as a message contentassociated with the image 60 of the user. The same applies to thefollowing conversation.

When the user inputs the message content 64 to the terminal device 10 asdescribed above, the specifying unit 30 may identify the multifunctiondevice (B) as a device to be used, and the control unit 26 may switchthe image 58 associated with the automatic response AI to the image 66associated with the multifunction device (B). The automatic response AIidentifies the request of the user by analyzing the message content ofthe user, and, when a reply is required, creates a reply such as ananswer to the request. The control unit 26 displays the character stringindicating the reply in the display area 56 a as a message content ofthe automatic response AI. The automatic response AI may searchinformation using the Internet or the like and analyze the results ofthe search, or may acquire information on the devices 12 and 14 andanalyze the information. The automatic response AI may reflect theresults of the analysis in the reply. Further, the automatic response AImay manage history of use of various applications by the user, historyof operation of the terminal device 10 by the user, history of use ofthe devices 12 and 14 by the user, and the like. Further, the automaticresponse AI may communicate with another automatic response AI stored inthe other device and acquire information from that automatic responseAI. The automatic response AI may reflect information managed oracquired by itself in the reply.

In response to the above message content 68, the user input a processcontent to be performed using the multifunction device (B) to theterminal device 10 as a message content of the user. In the exampleillustrated in FIG. 8, a message content 70 indicating the processcontent such as “I want to print a file X” is input to the terminaldevice 10 as a message content of the user.

The control unit 26 analyzes the message content 70 of the user tospecify the process content requested by the user, and causes themultifunction device (B) to execute the process content. For example,the control unit 26 transmits a print job including the data of file Xto the multifunction device (B). The multifunction device (B) thatreceives the print job prints the file X according to the print job. Thecontrol unit 26 may cause the UI unit 20 to display a screen for settingprinting conditions (for example, conditions such as the number ofprinting units, color printing, and black and white printing). The printjob includes the conditions set on the screen, and the multifunctiondevice (B) prints according to the conditions.

When the printing of the file X is completed, the control unit 26displays a message content 72 indicating that the printing has beencompleted, in the display area 56 a as a message content of themultifunction device (B). Even in this case, the control unit 26displays the device image 66 associated with the multifunction device(B) in the display area 56 a, and displays the message content 72 in thedisplay area 56 a as a message content associated with the device image66 of the multifunction device (B). The message content 72 itself is amessage content created by the general-purpose automatic response AI.

When the user (the terminal device 10) moves out of the area 50 of themultifunction device (B), the control unit 26 displays the image 58associated with the general-purpose automatic response AI in the displayarea 56 a as an image associated with the conversation partner, in placeof the device image 66 associated with the multifunction device (B).Further, the control unit 26 displays a message content 74 indicating acommon question such as “How can I help you?” in the display area 56 aas a message content of the automatic response AI.

As described above, according to the first exemplary embodiment, whenthe user (the terminal device 10) exists in an area of a device, thedevice is identified as a device to be used, and the display of aconversation partner who is responding is switched to the display of thedevice. In this manner, the user may visually confirm the conversationpartner who is responding.

When the user exists in the area of the device, the display of theconversation partner may be switched from the display of thegeneral-purpose automatic response AI to the display of the device, andthe automatic response AI (for example, the program) as a conversationpartner for the user may be switched from the general-purpose automaticresponse AI to an automatic response AI equipped in the device.

In the example illustrated in FIG. 8, when the automatic response AI isequipped in the multifunction device (B) (when a program of theautomatic response AI is installed in the multifunction device (B)), thecontrol unit 26 switches the automatic response AI as a conversationpartner for the user from the general-purpose automatic response AIequipped in the terminal device 10 (the program of the automaticresponse AI installed in the terminal device 10) to the automaticresponse AI equipped in the multifunction device (B).

In this case, the control unit 26 transmits the information indicatingthe message contents of the user to the multifunction device (B) via thecommunication path N. The automatic response AI equipped in themultifunction device (B) receives the information indicating the messagecontents of the user transmitted from the terminal device 10, analyzesthe message contents of the user, and creates a reply such as an answerto the message contents. The automatic response AI of the multifunctiondevice (B) transmits information indicating the message contentsincluding the reply to the terminal device 10. For example, the messagecontents 68 and 72 illustrated in FIG. 8 are created by the automaticresponse AI equipped in the multifunction device (B), and informationindicating the message contents 68 and 72 is transmitted from themultifunction device (B) to the terminal device 10. The control unit 26displays the message contents (for example, the message contents 68 and72) transmitted from the multifunction device (B) as a message contentof the multifunction device (B) in the display area 56 a in associationwith the device image 66 of the multifunction device (B).

When the user moves out of the area 50 of the multifunction device (B),the control unit 26 switches the image associated with the conversationpartner from the device image 66 associated with the multifunctiondevice (B) to image 58 associated with the general-purpose automaticresponse AI as illustrated in FIG. 8, and switch the automatic responseAI as a conversation partner for the user from the automatic response AIequipped in the multifunction device (B) to the general-purposeautomatic response AI equipped in the terminal device 10.

In the case where the automatic response AI is equipped in the device,the conversation is made between the automatic response AI and the userby performing the above process. Therefore, during that time, the loadof the process of the automatic response AI equipped in the terminaldevice 10 is reduced. Further, when the automatic response AI equippedin the device has a higher level of control and information collectioncapability than that of the general-purpose automatic response AI, theautomatic response AI equipped in the device may provide the user withmore useful information by making a conversation with the user as theconversation partner for the user.

(Modification 1)

Hereinafter, Modification 1 will be described. In Modification 1, thecontrol unit 26 controls the output of an instruction related to adevice to the conversation partner who is responding, depending on theposition of the user. For example, when the user exists in the area ofthe device, the control unit 26 receives an instruction related to thedevice from the user. Meanwhile, when the user exists outside the areaof the device, the control unit 26 does not receive an instructionrelated to the device from the user. In this manner, when the userexists in the area of the device, the user is able to give instructionsto the device, and when the user exists outside the area of the device,the user is not able to give instructions to the device. Since the areawhere instructions are able to be given to the device is limited, thesecurity of the device may be improved. For example, the security of thedevice may be improved by setting the area of the device such that onlyusers who stay in a specific room in the office are able to giveinstructions to the device installed in the specific room.

For example, as illustrated in FIG. 7, when the user exists in the area50 of the multifunction device (B) (see the user 52), the control unit26 receives the user's instruction to the multifunction device (B). Theuser may instruct the multifunction device (B) to execute a process suchas printing by using the UI unit 20 of the terminal device 10.Meanwhile, when the user exists outside the area 50 of the multifunctiondevice (B) (see the user 54), the control unit 26 does not receive theuser's instruction to the multifunction device (B). In this case, theuser may not give an instruction to execute a process such as printing,to the multifunction device (B). In this manner, it is possible toconstruct a secure environment for the multifunction device (B).

In Modification 1, when the user exists in an area of a device, thecontrol unit 26 may or may not switch the image associated with theconversation partner from the image associated with the general-purposeautomatic response AI to an image associated with the device.

Second Exemplary Embodiment

Hereinafter, a second exemplary embodiment will be described. In thefirst exemplary embodiment, one device is identified. In the secondexemplary embodiment, however, plural devices are identified.Hereinafter, the second exemplary embodiment will be described indetail.

A positional relationship between the device and the user (the terminaldevice 10) will be described with reference to FIG. 9. FIG. 9illustrates the positional relationship. Similarly to the firstexemplary embodiment, an area is defined for each device. For example,an area 50 is defined for the multifunction device (B) as a device 48,and an area 78 is defined for the PC (A) as a device 76. The areas 50and 78 may have the same size and the same shape as each other, or mayhave different sizes and different shapes from each other.

A user 80 is a user who exists in both areas 50 and 78. That is, theareas 50 and 78 partially overlap with each other, and the user 80 is auser who exists in the overlapping area. A user 82 is a user who existsin the area 50 and exists outside the area 78. A user 84 is a user whoexists in the area 78 and exists outside the area 50.

The specifying unit 30 identifies the respective positions of theterminal device 10, the multifunction device (B), and the PC (A) basedon the position information of each of the terminal device 10, themultifunction device (B), and the PC (A), and also identifies the areas50 and 78.

The specifying unit 30 may calculate the distance between themultifunction device (B) and the user (the terminal device 10) based onthe position information of the multifunction device (B) and theposition information of the user, and similarly, the specifying unit 30may calculate the distance between the PC (A) and the user based on theposition information of the PC (A) and the position information of theuser. When the distance between the multifunction device (B) and theuser is equal to or less than a threshold value, the specifying unit 30determines that the user exists in the area 50 of the multifunctiondevice (B). When the distance exceeds the threshold value, thespecifying unit 30 determines that the user exists outside the area 50of the multifunction device (B). Similarly, when the distance betweenthe PC (A) and the user is equal to or less than a threshold value, thespecifying unit 30 determines that the user exists in the area 78 of thePC (A). When the distance exceeds the threshold value, the specifyingunit 30 determines that the user exists outside the area 78 of the PC(A). The threshold value that regulates the positional relationshipbetween the multifunction device (B) and the user and the thresholdvalue that regulates the positional relationship between the PC (A) andthe user may be the same as each other or may be different from eachother. That is, the same threshold value or a different threshold valuemay be used for each device.

Hereinafter, a screen displayed on the terminal device 10 will bedescribed with reference to FIG. 10. FIG. 10 illustrates a screen 56.The screen 56 displays an image 58 associated with the automaticresponse AI and an image 60 associated with the user are displayed as inFIG. 8, and further displays information indicating the conversationbetween the user and the automatic response AI.

When the chatting program is activated, a message content 86 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a, as in the first exemplaryembodiment.

The position information acquiring unit 28 acquires position informationof the terminal device 10 and position information of each device andspecifies the positional relationship between the terminal device 10(user) and each device based on the position information of the terminaldevice 10 and the position information of each device.

For example, as illustrated in FIG. 9, it is assumed that the user (theterminal device 10) exists in both areas 50 and 78 (see the user 80).That is, it is assumed that the user exists in an area where the areas50 and 78 overlap each other. In this case, the specifying unit 30determines that the user (the terminal device 10) exists in the area 50of the multifunction device (B) based on the position information of theterminal device 10 and the multifunction device (B). In addition, thespecifying unit 30 determines that the user (the terminal device 10)exists in the area 78 of the PC (A) based on the position information ofthe terminal device 10 and the PC (A). The specifying unit 30 maydetermine that the user (the terminal device 10) exists in the area 50of the multifunction device (B) when the distance between the terminaldevice 10 and the multifunction device (B) is equal to or less than thethreshold value, and may determine that the user (the terminal device10) exists in the area 78 of the PC (A) when the distance between theterminal device 10 and the PC (A) is equal to or less than the thresholdvalue.

When the user (the terminal device 10) exists in the area 50 of themultifunction device (B), the specifying unit 30 identifies themultifunction device (B) as a candidate of a device to be used andspecifies a function associated with the device identificationinformation included in the position information of the multifunctiondevice (B), for example, in the device function management tableillustrated in FIG. 5. Therefore, the function that the multifunctiondevice (B) has is identified. Similarly, when the user (the terminaldevice 10) exists in the area 78 of the PC (A), the specifying unit 30identifies the PC (A) as a candidate of a device to be used andspecifies a function associated with the device identificationinformation included in the position information of the PC (A), forexample, in the device function management table illustrated in FIG. 5.Therefore, the function that the PC (A) has is identified.

When plural devices are identified as described above, the control unit26 displays a stock area 88 in the display area 56 b for the user anddisplays device images in the stock area 88. The stock area 88 is anarea where information on the candidate of the device to be used isdisplayed. In the example illustrated in FIG. 10, the device images aredisplayed as an example of candidate information. For example, thecontrol unit 26 displays the device images associated with the devicesidentified as described above in the stock area 88. In the exampleillustrated in FIG. 10, device images 90 and 92 are displayed in thestock area 88. The device image 90 is an image associated with themultifunction device (B) as a device. The device image 92 is an imageassociated with the PC (A) as a device. When the devices are identifiedin this manner, the control unit 26 displays device images associatedwith the devices in the stock area 88. Of course, the control unit 26may display character information indicating the identified devices inthe stock area 88, in place of the device images or along with thedevice images.

When the user exists only in the area 50 of the multifunction device(B), only the device image 90 associated with the multifunction device(B) is displayed in the stock area 88. Similarly, when the user existsonly in the area 78 of the PC (A), only the device image 92 associatedwith the PC (A) is displayed in the stock area 88.

The device image 90 may be an image generated by capturing themultifunction device (B) (an image having a size at the time of imagecapturing, or an enlarged or reduced image), or a schematic image (forexample, an icon) associated with the multifunction device (B).Similarly, the device image 92 may be an image generated by capturingthe PC (A), or a schematic image associated with the PC (A).

When a schematic image is used, the specifying unit 30 specifies aschematic image associated with the identified device by referring tothe device function management table illustrated in FIG. 5. Theschematic image is displayed as a device image. The data of theschematic image may be stored in the terminal device 10 or may be storedin an external device such as the server 16.

In the case of using image data generated by capturing a device, theexternal appearance of the current device itself (for example, anexternal appearance reflecting scratches, memo, or a seal affixed to thedevice, etc.) is reflected in the image, so that the user may see thedifference visually from other similar devices.

Further, when there are other device images that cannot be all displayedin the stock area 88, the user performs a scroll operation on the deviceimages displayed in the stock area 88, as indicated by an arrow 94, suchthat the other device images are displayed in the stock area 88.

The user may select an image associated with the device to be used (thedevice image 90 in the example illustrated in FIG. 10) from the stockarea 88 and move the device image 90 out of the stock area 88 asindicated by an arrow 96, so that the device image 90 may be transmittedto the automatic response AI as a message content of the user. Forexample, the user performs a drag operation to move the device image 90from the stock area 88 to a position where the message content of theuser is displayed, and performs a drop operation at the display positionof the message content. With these operations, the control unit 26transmits the device image 90 to the automatic response AI as a messagecontent of the user. For example, when the user selects an image (forexample, the device image 90) on the screen 56 and picks up the imagefrom the stock area 88 using a pointer (for example, a user's finger,pen, or stylus), so that the image is included in the message content ofthe user and transmitted to the automatic response AI. The control unit26 detects the contact of the pointer on the screen 56 and detects themovement of the indicator on the screen 56. The user may input characterinformation or voice information indicating a device to be used to theterminal device 10 so that information indicating the device to be usedis transmitted to the automatic response AI.

As described above, when a device to be used is designated by the user,the control unit 26 switches the display of the conversation partnerfrom the display of the general-purpose automatic response AI to thedisplay of the device. In the example illustrated in FIG. 10, since theuser designates the multifunction device (B) as a device to be used bydesignating the device image 90, the control unit 26 displays the deviceimage 66 associated with the multifunction device (B) in the displayarea 56 a as an image associated with the conversation partner, in placeof the image 58 associated with the automatic response AI.

Then, similarly to the first exemplary embodiment, the control unit 26also displays a message content 98 such as “Which function do you wantto use?” in the display area 56 a as a message content of themultifunction device (B).

When the user (the terminal device 10) moves out of the area 50 of themultifunction device (B), the control unit 26 displays the image 58associated with the general-purpose automatic response AI in the displayarea 56 a as an image associated with the conversation partner, in placeof the device image 66 associated with the multifunction device (B).Further, the control unit 26 deletes the device image 90 associated withthe multifunction device (B) from the stock area 88. When the user (theterminal device 10) moves out of the area 78 of the PC (A), the controlunit 26 deletes the device image 92 associated with the PC (A) from thestock area 88. When the user moves into an area of a new device, the newdevice is identified as a candidate of a device to be used, andinformation of the new device (for example, a device image associatedwith the new device) is displayed in the stock area 88.

As described above, according to the second exemplary embodiment, whenthe user (the terminal device 10) exists in an area of plural devices,the plural devices are identified as a candidate of a device to be used,and the display of a conversation partner who is responding is switchedto the display of a device selected from the plural devices by the user.In this manner, the user may visually confirm the conversation partnerwho is responding.

The display of the conversation partner may be switched from the displayof the general-purpose automatic response AI to the display of thedevice, and the automatic response AI (for example, the program) as aconversation partner for the user may be switched from thegeneral-purpose automatic response AI to an automatic response AIequipped in the device.

When the user exists in the area of plural devices, the specifying unit30 may identify a device closest to the user among the plural devices asthe device to be used, and the control unit 26 may switch the display ofthe general-purpose automatic response AI to the display of the deviceclosest to the user. For example, in the case where the user exists inboth areas of the multifunction device (B) and the PC (A), when themultifunction device (B) is installed closer to the user than the PC(A), the specifying unit 30 identifies the multifunction device (B) asthe device to be used. Further, the control unit 26 displays the deviceimage 66 associated with the multifunction device (B) in the displayarea 56 a as an image associated with the conversation partner, in placeof the image 58 associated with the general-purpose automatic responseAI.

(Modification 2)

Hereinafter, Modification 2 will be described. Similarly to Modification1, in Modification 2, the control unit 26 controls the output of aninstruction related to a device to the conversation partner who isresponding, depending on the position of the user. For example, when theuser exists in an area of plural devices, the control unit 26 receivesan instruction related to each of the plural devices from the user.

For example, as illustrated in FIG. 9, when the user exists in both ofthe area 50 of the multifunction device (B) and the area 78 of the PC(A) (see the user 80), the control unit 26 receives the user'sinstruction related to the multifunction device (B) and the PC (A). Forexample, the user may use the UI unit 20 of the terminal device 10 togive an execution instruction of a process such as printing to themultifunction device (B) and give the execution instruction of theprocess to the PC (A).

Further, when a device is selected from plural devices by the user, thecontrol unit 26 may receive an instruction related to the selecteddevice from the user. In the example illustrated in FIG. 10, the userexists in both areas of the multifunction device (B) and the PC (A), butthe multifunction device (B) is selected by the user. In this case, thecontrol unit 26 receives a user's instruction related to themultifunction device (B).

Further, when the user exists in an area of plural devices, the controlunit 26 may receive, from the user, an instruction related to a deviceclosest to the user among the plural devices. For example, in the casewhere the user exists in both areas of the multifunction device (B) andthe PC (A), when the multifunction device (B) is installed closer to theuser than the PC (A), the control unit 26 receives an instructionrelated to the multifunction device (B) from the user and does notreceive an instruction related to the PC (A) from the user.

According to Modification 2, when the user exists in an area of pluraldevices, it is possible to construct a secure environment for thedevices.

In Modification 1, when the user exists in an area of a device, thecontrol unit 26 may or may not switch the image associated with theconversation partner from the image associated with the general-purposeautomatic response AI to an image associated with the device.

Third Exemplary Embodiment

Hereinafter, a third exemplary embodiment will be described withreference to FIG. 11. FIG. 11 illustrates a screen 56. In the secondexemplary embodiment, one device is selected by the user. In the thirdexemplary embodiment, however, plural devices are selected by the user.

The screen 56 displays an image 58 associated with the automaticresponse AI and an image 60 associated with the user are displayed as inFIG. 8, and further displays information indicating the conversationbetween the user and the automatic response AI.

When the chatting program is activated, a message content 100 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

In the third exemplary embodiment, similarly to the second exemplaryembodiment described above, it is assumed that the user (the terminaldevice 10) exists in both areas 50 and 78 (see the user 80 in FIG. 9).That is, it is assumed that the user exists in an area where the areas50 and 78 overlap each other. In this case, a device image 90 associatedwith the multifunction device (B) and a device image 92 associated withthe PC (A) are displayed in the stock area 88.

For example, the user may select the device images 90 and 92 from thestock area 88 and move the device images 90 and 92 out of the stock area88, so that the device images 90 and 92 may be transmitted to theautomatic response AI as a message content of the user. In the exampleillustrated in FIG. 11, an image 102 in which the device images 90 and92 are displayed is generated, and the image 102 is transmitted to theautomatic response AI. The user may input character information or voiceinformation indicating plural devices to be used to the terminal device10 so that information indicating the plural devices to be used istransmitted to the automatic response AI.

As described above, when plural devices to be used are designated by theuser, the specifying unit 30 identifies the plural devices as devices tobe linked and specifies linkage functions associated with a combinationof the plural devices, for example, in the linkage function managementtable illustrated in FIG. 6. Therefore, the linkage functions executableusing the plural devices are identified.

In the above-described example, the specifying unit 30 identifies themultifunction device (B) associated with the device image 90 and the PC(A) associated with the device image 92 as devices to be linked andspecifies linkage functions (for example, a “scan transfer function” anda “print function”) associated with the combination of the PC (A) andthe multifunction device (B) in the linkage function management tableillustrated in FIG. 7. Therefore, the linkage functions executable usingthe PC (A) and the multifunction device (B) are identified. The “scantransfer function” is a function of transferring image data generated byscanning by the multifunction device (B) to the PC (A). The “printfunction” is a function of transmitting image data stored in the PC (A)to the multifunction device (B) and printing it with the multifunctiondevice (B). The process of specifying the devices and the linkagefunctions may be performed by the server 16.

Further, when plural devices to be used are designated by the user, thecontrol unit 26 switches the display of the conversation partner fromthe display of the general-purpose automatic response AI to the displayof the plural devices designated by the user.

In the above-described example, since the multifunction device (B) andthe PC (A) are designated as devices to be linked, the control unit 26displays the device image 66 associated with the multifunction device(B) and a device image 104 associated with the PC (A) in the displayarea 56 a as images associated with the conversation partner, in placeof the image 58 associated with the automatic response AI. The deviceimage 104 may be an image generated by capturing the PC (A) (forexample, an external appearance image of the PC (A)), or may be an imageimitating the PC (A) (for example, an icon). Of course, the control unit26 may display character strings indicating the multifunction device (B)and PC (A) in the display area 56 a as information indicating theconversation partner, in place of the device images 66 and 104 or alongwith the device images 66 and 104.

Further, the control unit 26 displays a message content 106 forconfirming the plural devices designated by the user in the display area56 a as a message content of the automatic response AI. In the casewhere the multifunction device (B) and the PC (A) are designated as thedevices to be linked, for example, a message content 106 such as“Multifunction device (B) and PC (A)?” is displayed as a message contentof the automatic response AI in the display area 56 a.

When the user approves with respect to the message content 106 (forexample, when the user issues a message content 108 such as “Yes”), thecontrol unit 26 displays the information on the linkage functionsexecutable using the PC (A) and the multifunction device (B) in thedisplay area 56 a as a message content 110 of the multifunction device(B) and the PC (A). The message content 110 itself is a message contentcreated by the general-purpose automatic response AI. The control unit26 displays the message content 110 in the display area 56 a as amessage content associated with the device image 66 of the multifunctiondevice (B) and the device image 104 of the PC (A), in order to act as ifthe multifunction device (B) and the PC (A) make the message content110. Since the linkage functions executable using the multifunctiondevice (B) and the PC (A) are the “scan transfer function” and the“print function” (see FIG. 6), the control unit 26 displays characterstrings or images indicating the “scan transfer function” and the “printfunction” in the display area 56 a as a message content of themultifunction device (B) and the PC (A).

When the user gives an execution instruction with respect to the messagecontent 110 by designating linkage functions by a message content 112,the control unit 26 (for example, the control unit 26 implemented by theautomatic response AI) receives the execution instruction and transmitsinformation indicating the execution instruction (execution instructioninformation) to the devices to be linked. As another example, a buttonimage for instructing the execution of the linkage functions isdisplayed on the screen 56, and the user may press the button image togive an execution instruction of the linkage functions. When the PC (A)and the multifunction device (B) are selected as the devices to belinked, the execution instruction information is transmitted to the PC(A) and the multifunction device (B). The PC (A) and the multifunctiondevice (B) that have received the execution instruction informationexecute the linkage functions indicated in the execution instructioninformation (the linkage functions designated by the user). For example,when the execution instruction of the “print function” is given as alinkage function, the PC (A) transmits image data to be printed to themultifunction device (B), and the multifunction device (B) prints theimage data on paper as a recording medium.

When the user (the terminal device 10) moves out of the areas 50 and 78,the control unit 26 displays the image 58 associated with thegeneral-purpose automatic response AI in the display area 56 a as animage associated with the conversation partner, in place of the images66 and 104. Further, the control unit 26 deletes the device image 90associated with the multifunction device (B) and the device image 92associated with the PC (A) from the stock area 88.

When the user moves out of the area 50 but exists in the area 78, thecontrol unit 26 may display the device image 104 in the display area 56a as an image associated with the conversation partner. In this case,similarly to the first exemplary embodiment, the specifying unit 30identifies the PC (A) as a device to be used. The same is true when theuser moves out of the area 78 but exists in the area 50.

As described above, according to the third exemplary embodiment, thedisplay of the conversation partner who is responding may be switched tothe display of the plural devices to be linked. In this manner, the usermay visually confirm the conversation partner who is responding.

When the user designates linkage functions by the message contents 112,the control unit 26 (automatic response AI) may cause the UI unit 20 todisplay a screen for controlling the devices to be linked (a remotecontrol screen), without giving the execution instruction of the linkagefunctions to the devices to be linked. The remote control screendisplays, for example, button images for instructing execution of thelinkage functions (for example, a button image for instructing executionof the “scan transfer image” and a button image for instructingexecution of the “print function”). When the user presses a button imageon the remote control screen, the linkage function associated with thebutton image is executed. Further, it is possible to set variousparameters on the remote control screen.

As another example, a remote control screen for controlling each deviceindividually may be displayed. For example, a remote control screen forcontrolling the multifunction device (B) and a remote control screen forcontrolling the PC (A) are displayed. The remote control screen for themultifunction device (B) displays button images for instructingexecution of solo functions that the multifunction device (B) has (forexample, a button image for instructing execution of the copy functionand a button image for instructing execution of the print function).Further, various parameters used in the multifunction device (B) may beset on the remote control screen for the multifunction device (B). Theremote control screen for the PC (A) displays, for example, data (files)stored in the PC (A) and the storage location (folders). Further, it ispossible to set various parameters used in the PC (A) on the remotecontrol screen for the PC (A). Further, it is possible to set and givesan instruction to execute the linkage functions (for example, the “scantransfer function” or the “print function” as a linkage function) onboth remote control screens.

When plural devices are displayed as conversation partners, theconversation partner of the user may be a general-purpose automaticresponse AI installed in the terminal device 10, or may be switched fromthe general-purpose automatic response AI to an automatic response AIequipped in the plural devices. For example, when an automatic responseAI is equipped in the multifunction device (B), the automatic responseAI equipped in the multifunction device (B) may function as aconversation partner, and when an automatic response AI is equipped inthe PC (A), the automatic response AI equipped in the PC (A) mayfunction as a conversation partner. When automatic response AIs areequipped in both of the multifunction device (B) and the PC (A), any oneof the automatic response AIs equipped in both of the multifunctiondevice (B) and the PC (A) may function as a conversation partner.

In the example illustrated in FIG. 11, information of two devices istransmitted to the automatic response AI, but information of three ormore devices (for example, three or more device images or characterstrings indicating three or more devices) may be transmitted to theautomatic response AI. In this case, in place of the image 58 associatedwith the automatic response AI, three or more device images aredisplayed as images associated with the conversation partners in thedisplay area 56 a.

Modifications 1 and 2 may be applied to the third exemplary embodiment.That is, when the user exists in an area of plural devices, the controlunit 26 receives an execution instruction of linkage functionsexecutable using the plural devices, and when the user does not exist inthe area of the plural devices, the control unit 26 does not receive anyexecution instruction of the linkage functions executable using theplural devices.

Fourth Exemplary Embodiment

Hereinafter, a fourth exemplary embodiment will be described withreference to FIG. 12. FIG. 12 illustrates a screen 56. The screen 56displays an image 58 associated with the automatic response AI and animage 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 114 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

In the fourth exemplary embodiment, similarly to the third exemplaryembodiment described above, it is assumed that the user (the terminaldevice 10) exists in both areas 50 and 78 (see the user 80 in FIG. 9).In this case, the specifying unit 30 identifies the multifunction device(B) and the PC (A) as devices to be linked and specifies linkagefunctions associated with the combination of the multifunction device(B) and the PC (A), for example, in the linkage function managementtable illustrated in FIG. 6. Therefore, the linkage functions executableusing the multifunction device (B) and the PC (A) are identified.

Further, since the user exists in both of the areas 50 and 78, thecontrol unit 26 displays the device image 66 associated with themultifunction device (B) and the device image 104 associated with the PC(A) in the display area 56 a as images associated with the conversationpartner, in place of the image 58 associated with the automatic responseAI. The control unit 26 displays a message content 118 for confirmingthat the multifunction device (B) and the PC (A) have been identified asdevices to be linked in the display area 56 a as a message content ofthe multifunction device (B) and the PC (A).

Further, when the user requests use of a device by making a message suchas “I want to use the multifunction device (B) and the PC (A)”, acharacter string indicating the request may be displayed as a messagecontent 116 of the user in the display area 56 b. When the user inputsthe message content 116 to the terminal device 10 as described above,the specifying unit 30 may identify the multifunction device (B) and thePC (A) as devices to be linked, and the control unit 26 may switch theimage 58 associated with the automatic response AI to the images 66 and104.

When the user approves with respect to the message content 118 (forexample, when the user issues a message content 120 such as “Yes”), thecontrol unit 26 displays the information on the linkage functionsexecutable using the PC (A) and the multifunction device (B) in thedisplay area 56 a as a message content 122 of the multifunction device(B) and the PC (A). The message content 122 itself is a message contentcreated by the general-purpose automatic response AI. The followingprocess is the same as that of the third exemplary embodiment describedabove.

As described above, according to the fourth exemplary embodiment, when auser exists in an area of plural devices, the display of theconversation partner who is responding is switched to the display of theplural devices. In this manner, the user may visually confirm theconversation partner who is responding.

In the fourth exemplary embodiment, the conversation partner may beswitched from the general-purpose automatic response AI to an automaticresponse AI equipped in the plural devices. Further, when the userexists in an area of three or more devices (that is, when the userexists in an area where areas of three or more devices overlap eachother), the display of the conversation partner is switched to thedisplay of the three or more devices.

(Display Example of Image Associated with Conversation Partner)

Hereinafter, a display example of an image associated with aconversation partner will be described with reference to FIGS. 13A to13E. FIGS. 13A to 13E illustrate the display example. Here, it isassumed that the user exists in an area of plural devices (for example,the multifunction device (B) and the PC (A)), and the plural devices areidentified as devices to be linked.

FIG. 13A illustrates images in the basic form. Similarly to the thirdexemplary embodiment described above, when the user exists in both areas50 and 78 (that is, when the user exists in an area where the areas 50and 78 overlap each other (see the user 80 in FIG. 9)), the device image66 associated with the multifunction device (B) and the device image 104associated with the PC (A) are displayed as images associated with theconversation partner in the display area 56 a.

In the state where the device images 66 and 104 are displayed as imagesassociated with the conversation partners as illustrated in FIG. 13A,when a message content 124 is displayed as a message content of themultifunction device (B) in the display area 56 a as illustrated in FIG.13B, the control unit 26 displays the device image 66 associated withthe multifunction device (B) in the display area 56 a, to be larger thanthe device image 104 associated with the PC (A). For example, when thePC (A) does not execute a process included in the linkage function butthe multifunction device (B) executes the process included in thelinkage function, information on the process is displayed as a messagecontent of the multifunction device (B) in the display area 56 a. Inthis case, the device image 66 is displayed larger than the device image104. In this manner, the user may visually confirm the device thatperforms the process included in the linkage function. In the case whereboth the multifunction device (B) and the PC (A) perform the processincluded in the linkage function, as illustrated in FIG. 13A, the deviceimages 66 and 104 are displayed with the same size as each other.

Meanwhile, when a message content 126 is displayed as a message contentof the PC (A) in the display area 56 a as illustrated in FIG. 13C, thecontrol unit 26 displays the device image 104 in the display area 56 a,to be larger than the device image 66. For example, when the PC (A)executes a process included in the linkage function but themultifunction device (B) does not execute the process included in thelinkage function, information on the process is displayed as a messagecontent of the PC (A) in the display area 56 a.

Further, in the example illustrated in FIG. 13A, the device images 66and 104 are displayed so as to be arranged side by side in the lateraldirection. However, as illustrated in FIG. 13D, the device images 66 and104 may be displayed so as to be arranged side by side in the verticaldirection. Of course, the device images 66 and 104 may be displayed inother arrangements.

Further, when a message content 128 is displayed as a message content ofthe multifunction device (B) in the display area 56 a as illustrated inFIG. 13E, the device image 66 associated with the multifunction device(B) may be displayed larger than the device image 104 associated withthe PC (A). When a message content is displayed as a message content ofthe PC (A) in the display area 56 a, the device image 104 is displayedlarger than the device image 66.

Further, the size and display order of the device images may be changeddepending on the positional relationship between each device and theuser. For example, the control unit 26 may display a device imageassociated with a device closer to the user in an enlarged manner, ormay display device images associated with respective devices in theorder of closeness to the user.

Further, the display order of the device images may be changed dependingon the message order of the user. For example, when the user makesmessages in the order of the “multifunction device (B)” and the “PC(A),” the device images 66 and 104 may be displayed in the order of thedevice image 66 associated with the multifunction device (B) and thedevice image 104 associated with the PC (A). For example, the previouslydesignated device (for example, the multifunction device (B)) may bedisplayed on the left or upper side, and the subsequently specifieddevice (for example, PC (A)) may be displayed on the right or lowerside. Of course, the order of display may be determined by the order ofdevice identification, the order of registration, etc., irrespective ofthe order of designation. Further, a device image of a device that ismaking a message (a device associated with a message content) may bedisplayed at a predetermined position (for example, the left side or theupper side). In this manner, the user may visually confirm the devicethat is making a message (for example, the device that performs aprocess).

(Access Process to Device)

Hereinafter, an operation when executing a linkage function will bedescribed. For example, when a linkage function is executed, an accessrequest is transmitted from the terminal device 10 to each device to belinked, and the terminal device 10 and each device to be linked areconnected. Hereinafter, the access process will be described withreference to FIG. 14. FIG. 14 is a sequence diagram illustrating theprocess.

When the multifunction device (B) and the PC (A) are identified as thedevices to be linked in the terminal device 10 (that is, when the userexists in the area of the multifunction device (B) and the PC (A)), theterminal device 10 transmits the information indicating the accessrequest to the devices to be linked (the multifunction device (B) andthe PC (A)) (S01). This transmission may be controlled by an automaticresponse AI. For example, when address information indicating theaddress of each of the devices to be linked is stored in the server 16,the terminal device 10 acquires the address information of each of thedevices to be linked from the server 16. In a case where the addressinformation is included in the device identification information, thecontrol unit 26 of the terminal device 10 may acquire the addressinformation from the device identification information of each device. Aprocess of acquiring the address information may be performed by anautomatic response AI. Of course, the address information of each devicemay be stored in the storage unit 24 of the terminal device 10. Theterminal device 10 may acquire the address information of each device byanother method. The terminal device 10 transmits the informationindicating the access request to each of the devices to be linked (forexample, the multifunction device (B) and the PC (A)) by using theaddress information of each of the devices to be linked.

The multifunction device (B) and the PC (A) that have received theinformation indicating the access request determine whether to permitthe access to the terminal device 10 (S02). For example, when themultifunction device (B) and the PC (A) correspond to devices that arenot permitted to connect, or when the number of devices requestingaccess exceeds the upper limit, access is not permitted. When the accessfrom the terminal device 10 is permitted, the changing operation may beprohibited such that setting information unique to each of themultifunction device (B) and the PC (A) is not changed from the terminaldevice 10. For example, it may be prohibited to change the colorparameters of the multifunction device (B), the setting time whenshifting to power saving, and the like. As a result, the security forthe device to be linked is improved. As another example, when linkingdevices, change of setting information may be restricted as comparedwith a case where the devices are used alone without being linked. Forexample, it may be permitted to change a smaller number of setting itemsas compared with the case where the device is used alone. In addition,browsing of other users' personal information such as the operationhistory may be prohibited. As a result, the security for the user'spersonal information is improved.

Result information indicating permission or non-permission of the accessis transmitted from the multifunction device (B) and the PC (A) to theterminal device 10 (S03). When the access to the multifunction device(B) and the PC (A) is permitted, communication is established betweenthe terminal device 10 and the multifunction device (B), and furthercommunication is established between the terminal device 10 and the PC(A).

Next, in the terminal device 10, the user instructs execution of alinkage function (for example, a “print function”) (S04). The terminaldevice 10 transmits information indicating the execution instruction ofthe linkage function (execution instruction information) to each of thedevices to be linked (the multifunction device (B) and the PC (A))according to the instruction (S05). This transmission may be controlledby an automatic response AI. The execution instruction informationtransmitted to the multifunction device (B) includes informationindicating a process to be executed by the multifunction device (B) (forexample, job information), and the execution instruction informationtransmitted to the PC (A) includes information indicating a process tobe executed by the PC (A) (for example, job information).

The multifunction device (B) and the PC (A) that have received theexecution instruction information execute the linkage function (forexample, the “print function”) according to the execution instructioninformation (S06). When the linkage function to be executed includes aprocess of transmitting and receiving data between the multifunctiondevice (B) and the PC (A), communication is established between themultifunction device (B) and the PC (A). For example, the executioninstruction information transmitted to the multifunction device (B)includes address information of the PC (A), and the executioninstruction information transmitted to the PC (A) includes addressinformation of the multifunction device (B). Communication isestablished between the multifunction device (B) and the PC (A) usingthese pieces of address information. After the communication isestablished, the PC (A) transmits image data to be printed to themultifunction device (B), and the multifunction device (B) prints theimage data on paper as a recording medium.

When the execution of the linkage function is completed, informationindicating completion of execution of the linkage function istransmitted from the multifunction device (B) and the PC (A) to theterminal device 10 (S07). Information indicating that execution of thelinkage function has been completed is displayed on the UI unit 20 ofthe terminal device 10 (S08). When information indicating completion ofexecution is not displayed even though a preset time has elapsed sincethe execution instruction is given, the control unit 26 of the terminaldevice 10 may cause the UI unit 20 to display information indicating anerror, and again transmit execution instruction information orinformation indicating an access request to the multifunction device (B)and the PC (A).

Next, the user confirms whether or not to release the linked statebetween the multifunction device (B) and the PC (A) (S09), and a processis executed according to the presence or absence of the release (S10).When releasing the linked state, the user gives an instruction ofrelease by using the terminal device 10. Therefore, the communicationbetween the terminal device 10 and the multifunction device (B) isreleased, and further the communication between the terminal device 10and the PC (A) is released. Similarly, the communication between themultifunction device (B) and the PC (A) is released as well. When thelinked state is not to be released, the execution instruction may begiven continuously.

Modifications 1 and 2 may be applied to the fourth exemplary embodiment.That is, when the user exists in an area of plural devices, the controlunit 26 receives an execution instruction of linkage functionsexecutable using the plural devices, and when the user does not exist inthe area of the plural devices, the control unit 26 does not receive anyexecution instruction of the linkage functions executable using theplural devices.

Fifth Exemplary Embodiment

Hereinafter, a fifth exemplary embodiment will be described. In thefifth exemplary embodiment, the display of the conversation partner isswitched to the display of the function depending on the position of theuser. For example, depending on the position of the user, usablefunctions (for example, functions implemented by software or functionsimplemented by the device) change, and thus, the display of theconversation partner is switched to the display of a function.

For example, management information indicating association between anarea and a usable function in the area is prepared in advance, and themanagement information is stored in the storage unit 24 of the terminaldevice 10. Of course, the management information may not be stored inthe terminal device 10 but may be stored in an external device such asthe server 16. The specifying unit 30 identifies the position of theterminal device 10 (the user) based on the position information of theterminal device 10 acquired by the position information acquiring unit28 and specifies a function associated with the area including theposition of the user in the management information. This function is afunction that is usable by the terminal device 10 in the place where theuser exists. For example, a function that is usable only in a specificoffice is determined, and the position of the specific office and thefunction are associated with each other and registered in the managementinformation. When the user exists in the specific office, the terminaldevice 10 is enabled to use the function associated with the specificoffice.

When the function is implemented by software, the usable software may besoftware installed in the terminal device 10, or may be softwareinstalled in an external device such as the server 16. When the softwareis installed in an external device, a function for the software isprovided to the terminal device 10 via a communication path.

Hereinafter, the fifth exemplary embodiment will be described in detailwith reference to FIG. 15. FIG. 15 illustrates a screen 56. The screen56 displays an image 58 associated with the automatic response AI and animage 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 130 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a, as in the first exemplaryembodiment.

The position information acquiring unit 28 acquires position informationof the terminal device 10 (the user), and the specifying unit 30identifies the position of the terminal device 10 based on the positioninformation. For example, when the user exists in an area where apassword function is usable, the specifying unit 30 determines that theuser (terminal device 10) exists in an area where the password functionis usable, based on the position information of the terminal device 10.The password function is a function implemented by password settingsoftware.

When the user (the terminal device 10) exists in an area where thepassword function is usable, the specifying unit 30 identifies thepassword function as a function to be used.

When the user (the terminal device 10) exists in an area of a function,the control unit 26 switches the display of the conversation partnerfrom the display of the general-purpose automatic response AI to thedisplay of the function (for example, an image associated with thefunction or a character string indicating the function).

In the above-described example, since the user exists in the area of thepassword function, the control unit 26 displays a function image 134associated with the password function in the display area 56 a as animage associated with the conversation partner, in place of the image 58associated with the automatic response AI.

The function image may be, for example, an image associated withsoftware (an application, etc.) or an image associated with a device inwhich a process is performed (a device present in the real space). Thefunction image is, for example, an image such as an icon, which may beregarded as a virtual image in the sense of distinguishing an imagerepresenting an actual external appearance of a device as hardware (forexample, a photograph) or an image representing the device itself. Thefunction image 134 is an image associated with the password settingsoftware.

The control unit 26 may display a character string indicating thepassword function in the display area 56 a as information indicating theconversation partner, in place of the function image 134 or along withthe function image 134.

Further, the control unit 26 displays a message content 136 such as“Which file do you want to set a password?” in the display area 56 a asa message content of the password setting software. The message content136 itself is a message content created by the general-purpose automaticresponse AI. The control unit 26 displays the message content 136 in thedisplay area 56 a as a message content associated with the functionimage 134 of the password setting software, in order to act as if thepassword setting software makes the message content 136.

Further, when the user requests use of a function by making a messagesuch as “I want to use the password function”, a character stringindicating the request may be displayed as a message content 132 of theuser in the display area 56 b.

When the user inputs the message content 132 to the terminal device 10as described above, the specifying unit 30 may identify the passwordfunction as a function to be used, and the control unit 26 may switchthe image 58 associated with the automatic response AI to the functionimage 134 associated with the password function.

For the above message content 136, the user designates a file to beprocessed. In the example illustrated in FIG. 15, a message content 138indicating a “file X” as an object to be processed is input to theterminal device 10 as a message content of the user.

The control unit 26 specifies the file X to be processed by analyzingthe message content 138 of the user. The control unit 26 activatespassword setting software and sets a password to the file X by thepassword setting software.

When the setting of the password is completed, the control unit 26displays a message content 140 indicating that the setting of thepassword has been completed, in the display area 56 a as a messagecontent of the password setting software. Even in this case, the controlunit 26 displays the function image 134 associated with the passwordfunction in the display area 56 a, and displays the message content 140in the display area 56 a as a message content associated with thefunction image 134 of the password function. The message content 140itself is a message content created by the general-purpose automaticresponse AI.

When the user (the terminal device 10) moves out of the area of thepassword function, the control unit 26 displays the image 58 associatedwith the general-purpose automatic response AI in the display area 56 aas an image associated with the conversation partner, in place of thefunction image 134 associated with the password function. Further, thecontrol unit 26 displays a message content 142 indicating a commonquestion such as “How can I help you?” in the display area 56 a as amessage content of the automatic response AI.

As described above, according to the fifth exemplary embodiment, whenthe user (the terminal device 10) exists in an area of a function, thefunction is identified as a function to be used, and the display of aconversation partner who is responding is switched to the display of thefunction. In this manner, the user may visually confirm the conversationpartner who is responding.

When an automatic response AI is assigned for each function, the displayof the conversation partner may be switched from the display of thegeneral-purpose automatic response AI to the display of the function,and the automatic response AI (for example, the program) as aconversation partner for the user may be switched from thegeneral-purpose automatic response AI to an automatic response AIassigned to the function.

(Modification 3)

Hereinafter, Modification 3 will be described. In Modification 3, thecontrol unit 26 controls the output of an instruction related to afunction to the conversation partner who is responding, depending on theposition of the user. For example, when the user exists in the area ofthe function, the control unit 26 receives an instruction related to thefunction from the user. Meanwhile, when the user exists outside the areaof the function, the control unit 26 does not receive an instructionrelated to the function from the user. In this manner, when the userexists in the area of the function, the user is able to giveinstructions to the function, and when the user exists outside the areaof the function, the user is not able to give instructions to thefunction. Since the area where instructions are able to be given to thefunction is limited, the security of the function may be improved. Forexample, the security of the function may be improved by setting thearea of the function such that only users who stay in a specific room inthe office are able to give instructions to the function associated withthe specific room.

For example, when the user exists in the area of the password function,the control unit 26 receives a user's instruction related to thepassword function. For example, the user may use the UI unit 20 of theterminal device 10 to give an instruction for a password setting processto the password setting software. Meanwhile, when the user existsoutside the area of the password function, the control unit 26 does notreceive a user's instruction related to the password function. In thiscase, the user is unable to give an instruction for the password settingprocess to the password setting software. In this manner, it is possibleto construct a secure environment for the password setting software.

In Modification 3, when the user exists in an area of a function, thecontrol unit 26 may or may not switch the image associated with theconversation partner from the image associated with the general-purposeautomatic response AI to an image associated with the function.

Sixth Exemplary Embodiment

Hereinafter, a sixth exemplary embodiment will be described withreference to FIG. 16. In the fifth exemplary embodiment, one function isidentified. In the sixth exemplary embodiment, however, plural functionsare identified.

FIG. 16 illustrates a screen 56. The screen 56 displays an image 58associated with the automatic response AI and an image 60 associatedwith the user are displayed as in FIG. 8, and further displaysinformation indicating the conversation between the user and theautomatic response AI.

When the chatting program is activated, a message content 144 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a, as in the first exemplaryembodiment.

The position information acquiring unit 28 acquires position informationof the terminal device 10, and the specifying unit 30 identifies theposition of the terminal device 10 based on the position information.

For example, it is assumed that the user exists in both of an area wherea password function is usable and an area where a data transmissionfunction is usable. That is, it is assumed that the user exists in anarea where the area of the password function and the area of the datatransmission function overlap each other. In this case, the specifyingunit 30 determines that the user (the terminal device 10) exists in thearea where the password function is usable, based on the positioninformation of the terminal device 10. Further, the specifying unit 30determines that the user (the terminal device 10) exists in the areawhere the data transmission function is usable, based on the positioninformation of the terminal device 10. The data transmission function isa function implemented by data transmission software.

When the user (the terminal device 10) exists in the area of thepassword function, the specifying unit 30 identifies the passwordfunction as a candidate of a function to be used. Similarly, when theuser (the terminal device 10) exists in the area of the datatransmission function, the specifying unit 30 identifies the datatransmission function as a candidate of a function to be used.

When plural functions are identified as described above, the controlunit 26 displays a stock area 146 in the display area 56 b for the userand displays function images in the stock area 146. The stock area 146is an area where information on the candidates of a function to be usedis displayed. In the example illustrated in FIG. 16, the function imagesare displayed as an example of candidate information. For example, thecontrol unit 26 displays the function images associated with thefunctions identified as described above, in the stock area 146. In theexample illustrated in FIG. 16, function images 148 and 150 aredisplayed in the stock area 146. The function image 148 is an imageassociated with the password function (password setting software). Thefunction image 150 is an image associated with the data transmissionfunction (data transmission software). When the functions are identifiedin this manner, the control unit 26 displays function images associatedwith the functions in the stock area 146. Of course, the control unit 26may display character information indicating the identified functions inthe stock area 146, in place of the function images or along with thefunction images.

When the user exists only in the area of the password function, only thefunction image 148 associated with the password function is displayed inthe stock area 146. Similarly, when the user exists only in the area ofthe data transmission function, only the function image 150 associatedwith the data transmission function is displayed in the stock area 146.

Further, when there are other function images that cannot be alldisplayed in the stock area 146, the user performs a scroll operation onthe function images displayed in the stock area 146 such that the otherdevice images are displayed in the stock area 146.

The user may select an image associated with the function to be used(the function image 148 in the example illustrated in FIG. 16) from thestock area 146 and move the function image 148 out of the stock area146, so that the function image 148 may be transmitted to the automaticresponse AI as a message content of the user. The user may inputcharacter information or voice information indicating a function to beused to the terminal device 10 so that information indicating thefunction to be used is transmitted to the automatic response AI.

As described above, when a function to be used is designated by theuser, the control unit 26 switches the display of the conversationpartner from the display of the general-purpose automatic response AI tothe display of the function. In the example illustrated in FIG. 16,since the user designates the password function as a function to be usedby designating the function image 148, the control unit 26 displays thefunction image 134 associated with the password function in the displayarea 56 a as an image associated with the conversation partner, in placeof the image 58 associated with the automatic response AI.

Then, similarly to the fifth exemplary embodiment, the control unit 26displays a message content 152 such as “Which file do you want to set apassword?” in the display area 56 a as a message content of themultifunction device (B).

When the user (the terminal device 10) moves out of the area of thepassword function, the control unit 26 displays the image 58 associatedwith the general-purpose automatic response AI in the display area 56 aas an image associated with the conversation partner, in place of thefunction image 134 associated with the password function. Further, thecontrol unit 26 deletes the function image 148 associated with thepassword function from the stock area 146. When the user (the terminaldevice 10) moves out of the area of the data transmission function, thecontrol unit 26 deletes the function image 150 associated with the datatransmission function from the stock area 146. When the user moves intoan area of a new function, the new function is identified as a candidateof a function to be used, and information of the new function (forexample, a function image associated with the new function) is displayedin the stock area 146.

As described above, according to the sixth exemplary embodiment, whenthe user (the terminal device 10) exists in an area of plural functions,the plural functions are identified as candidates of a function to beused, and the display of a conversation partner who is responding isswitched to the display of a function selected from the plural functionsby the user. In this manner, the user may visually confirm theconversation partner who is responding.

The display of the conversation partner may be switched from the displayof the general-purpose automatic response AI to the display of thefunction, and the automatic response AI (for example, the program) as aconversation partner for the user may be switched from thegeneral-purpose automatic response AI to an automatic response AIassigned to the function.

When the user exists in the area of plural functions, the specifyingunit 30 may identify a function closest to the user among the pluralfunctions as the function to be used, and the control unit 26 may switchthe display of the general-purpose automatic response AI to the displayof the function closest to the user.

(Modification 4)

Hereinafter, Modification 4 will be described. Similarly to Modification3, in Modification 4, the control unit 26 controls the output of aninstruction related to a function to the conversation partner who isresponding, depending on the position of the user. For example, when theuser exists in an area of plural functions, the control unit 26 receivesan instruction related to each of the plural functions from the user.

For example, when the user exists in both the area of the passwordfunction and the area of the data transmission function, the controlunit 26 receives a user's instruction related to the password functionand the data transmission function. The user may use the UI unit 20 ofthe terminal device 10 to give an instruction for the password settingprocess to the password setting software and give an instruction for adata transmitting process to the data transmission software.

Further, similarly to the sixth exemplary embodiment described above,when a function is selected from plural functions by the user, thecontrol unit 26 may receive an instruction related to the selectedfunction from the user. In the example illustrated in FIG. 16, the userexists in both areas of the password function and the data transmissionfunction, but the password function is selected by the user. In thiscase, the control unit 26 receives a user's instruction related to thepassword function.

Further, when the user exists in an area of plural functions, thecontrol unit 26 may receive, from the user, an instruction related to afunction closest to the user among the plural functions.

According to Modification 4, when the user exists in an area of pluralfunctions, it is possible to construct a secure environment for thefunctions.

In Modification 4, when the user exists in an area of a function, thecontrol unit 26 may or may not switch the image associated with theconversation partner from the image associated with the general-purposeautomatic response AI to an image associated with the function.

Seventh Exemplary Embodiment

Hereinafter, a seventh exemplary embodiment will be described. In thesixth exemplary embodiment, one function is selected by the user. In theseventh exemplary embodiment, however, plural functions are selected bythe user.

FIG. 17 illustrates an exemplary linkage function management tableaccording to the seventh exemplary embodiment. The linkage functionmanagement table is information indicating linkage functions executableusing plural functions. In the linkage function management table, as anexample, a combination of function IDs (for example, a combination ofIDs for identifying software), information indicating function names(for example, software names), and information indicating linkagefunctions executable using plural functions are associated with eachother. The linkage functions executable using plural functions arespecified by referring to the linkage function management table.

For example, software a as a function is software that transmits data,and software 13 as a function is software that locks the data with apassword. For example, a linkage function of transmitting data aftersetting a password for the data is implemented by combining the softwarea and the software 13. For other software, executable linkage functionsare similarly specified.

A linkage function executable using three or more functions (forexample, software) may be specified. In this case, a combination ofthree or more functions and a linkage function are associated with eachother, and the association is registered in the linkage functionmanagement table.

FIG. 18 illustrates a screen 56. The screen 56 displays an image 58associated with the automatic response AI and an image 60 associatedwith the user are displayed as in FIG. 8, and further displaysinformation indicating the conversation between the user and theautomatic response AI.

When the chatting program is activated, a message content 154 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

In the seventh exemplary embodiment, similarly to the sixth exemplaryembodiment described above, it is assumed that the user (the terminaldevice 10) exists in both an area of a password function and an area ofa data transmission function. In this case, a function image 148associated with the password function and a function image 150associated with the data transmission function are displayed in thestock area 146.

For example, the user may select the function images 148 and 150 fromthe stock area 146 and move the function images 148 and 150 out of thestock area 146, so that the function images 148 and 150 may betransmitted to the automatic response AI as a message content of theuser. In the example illustrated in FIG. 18, an image 156 in which thefunction images 148 and 150 are displayed is generated, and the image156 is transmitted to the automatic response AI. The user may inputcharacter information or voice information indicating plural functionsto be used to the terminal device 10 so that information indicating theplural functions to be used is transmitted to the automatic response AI.

As described above, when plural functions to be used are designated bythe user, the specifying unit 30 identifies the plural functions asfunctions to be linked and specifies linkage functions associated with acombination of the plural functions, for example, in the linkagefunction management table illustrated in FIG. 17. Therefore, the linkagefunctions executable using the plural functions are identified.

In the above-described example, the specifying unit 30 identifies thepassword function associated with the function image 148 and the datatransmission function associated with the function image 150 asfunctions to be linked and specifies linkage functions (for example, afunction of setting a password for data and transferring the data, etc.)associated with the combination of the password function and the datatransmission function in the linkage function management tableillustrated in FIG. 17. Therefore, the linkage functions executableusing the password function and the data transmission function areidentified. The process of specifying the functions and the linkagefunctions may be performed by the server 16.

Further, when plural functions to be used are designated by the user,the control unit 26 switches the display of the conversation partnerfrom the display of the general-purpose automatic response AI to thedisplay of the plural functions designated by the user.

In the above-described example, since the password function and the datatransmission function are designated as functions to be linked, thecontrol unit 26 displays the function image 134 associated with thepassword function and the function image 158 associated with the datatransmission function in the display area 56 a as images associated withthe conversation partner, in place of the image 58 associated with theautomatic response AI. Of course, the control unit 26 may displaycharacter strings indicating the password function and the datatransmission function in the display area 56 a as information indicatingthe conversation partner, in place of the function images 134 and 158 oralong with the function images 134 and 158.

Further, the control unit 26 displays a message content 160 forconfirming the plural functions designated by the user in the displayarea 56 a as a message content of the automatic response AI. In the casewhere the password function and the data transmission function aredesignated as the functions to be linked, for example, the messagecontent 160 such as “Password function and Data transmission function?”is displayed as a message content of the automatic response AI in thedisplay area 56 a.

When the user approves with respect to the message content 160 (forexample, when the user issues a message content 162 such as “Yes”), thecontrol unit 26 displays the information on the linkage functionsexecutable using the password function and the data transmissionfunction in the display area 56 a as a message content 164 of thepassword function and the data transmission function. The messagecontent 164 itself is a message content created by the general-purposeautomatic response AI. The control unit 26 displays the message content164 in the display area 56 a as a message content associated with thefunction image 134 of the password function and the function image 158of the data transmission function, in order to act as if the passwordfunction and the data transmission function make the message content164.

When the user gives an execution instruction with respect to the messagecontent 164 by designating linkage functions by a message content 166,the control unit 26 (for example, the control unit 26 implemented by theautomatic response AI) receives the execution instruction and controlsthe execution of the linkage functions. As another example, a buttonimage for instructing the execution of the linkage functions isdisplayed on the screen 56, and the user may press the button image togive an execution instruction of the linkage functions. For example, thecontrol unit 26 activates the password setting software and datatransmission software, sets a password to a file designated by the user,by the password setting software, and transmits the file set with thepassword to a transfer destination designated by the user, by the datatransmission software.

When the user (the terminal device 10) moves out of the area of thepassword function and the data transmission function, the control unit26 displays the image 58 associated with the general-purpose automaticresponse AI in the display area 56 a as an image associated with theconversation partner, in place of the function images 134 and 158.Further, the control unit 26 deletes the function image 148 associatedwith the password function and the function image 150 associated withthe data transmission function from the stock area 146.

When the user moves out of the area of the password function but existsin the area of the data transmission function, the control unit 26 maydisplay the function image 158 in the display area 56 a as an imageassociated with the conversation partner. In this case, the specifyingunit 30 identifies the data transmission function as a function to beused. The same is true when the user moves out of the area of the datatransmission function but exists in the area of the password function.

As described above, according to the seventh exemplary embodiment, thedisplay of the conversation partner who is responding may be switched tothe display of the plural functions to be linked. In this manner, theuser may visually confirm the conversation partner who is responding.

When plural functions are displayed as conversation partners, theconversation partner of the user may be a general-purpose automaticresponse AI equipped in the terminal device 10, or may be switched fromthe general-purpose automatic response AI to an automatic response AIassigned to each of the plural functions. For example, when theautomatic response AI assigned to the password function is stored in theterminal device 10 or the server 16, the automatic response AI assignedto the password function may function as a conversation partner.Similarly, when the automatic response AI assigned to the datatransmission function is stored in the terminal device 10 or the server16, the automatic response AI assigned to the data transmission functionmay function as a conversation partner. When both automatic response AIsof the password function and the data transmission function are stored,an automatic response AI of either the password function or the datatransmission function may function as a conversation partner.

In the example illustrated in FIG. 18, information of two functions istransmitted to the automatic response AI, but information of three ormore functions (for example, three or more function images or characterstrings indicating three or more functions) may be transmitted to theautomatic response AI. In this case, in place of the image 58 associatedwith the automatic response AI, three or more function images aredisplayed in the display area 56 a as images associated with theconversation partners. Further, the display example illustrated in FIGS.13A to 13E may be applied to the seventh exemplary embodiment.

Modifications 3 and 4 may be applied to the seventh exemplaryembodiment. That is, when the user exists in an area of pluralfunctions, the control unit 26 receives an execution instruction oflinkage functions executable using the plural functions, and when theuser does not exist in the area of the plural functions, the controlunit 26 does not receive any execution instruction of the linkagefunctions executable using the plural functions.

Eighth Exemplary Embodiment

Hereinafter, an eighth exemplary embodiment will be described withreference to FIG. 19. FIG. 19 illustrates a screen 56. The screen 56displays an image 58 associated with the automatic response AI and animage 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 168 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

In the eighth exemplary embodiment, similarly to the seventh exemplaryembodiment described above, it is assumed that the user (the terminaldevice 10) exists in both an area of a password function and an area ofa data transmission function. In this case, the specifying unit 30identifies the password function and the data transmission function asfunctions to be linked and specifies linkage functions associated withthe combination of the password function and the data transmissionfunction in the linkage function management table illustrated in FIG.17. Therefore, the linkage functions executable using the passwordfunction and the data transmission function are identified.

Further, since the user exists in both the area of the password functionand the area of the data transmission function, the control unit 26displays the function image 134 associated with the password functionand the function image 158 associated with the data transmissionfunction in the display area 56 a as images associated with theconversation partner, in place of the image 58 associated with theautomatic response AI. The control unit 26 displays a message content172 for confirming that the password function and the data transmissionfunction have been identified as functions to be linked in the displayarea 56 a as a message content of the password function and the datatransmission function.

Further, when the user requests use of functions by making a messagesuch as “I want to use the password function and the data transmissionfunction”, a character string indicating the request may be displayed asa message content 170 of the user in the display area 56 b. When theuser inputs the message content 170 to the terminal device 10 asdescribed above, the specifying unit 30 may identify the passwordfunction and the data transmission function as functions to be linked,and the control unit 26 may switch the image 58 associated with theautomatic response AI to the function images 134 and 158.

When the user approves with respect to the message content 172 (forexample, when the user issues a message content 174 such as “Yes”), thecontrol unit 26 displays the information on the linkage functionsexecutable using the password function and the data transmissionfunction, in the display area 56 a as a message content 176 of thepassword function and the data transmission function. The messagecontent 176 itself is a message content created by the general-purposeautomatic response AI. A linkage function to be executed is designatedby a message content 178 of the user. The following process is the sameas that of the seventh exemplary embodiment described above.

As described above, according to the eighth exemplary embodiment, when auser exists in an area of plural functions, the display of theconversation partner who is responding is switched to the display of theplural functions. In this manner, the user may visually confirm theconversation partner who is responding.

The conversation partner may be switched from the general-purposeautomatic response AI to an automatic response AI of the pluralfunctions. Further, when the user exists in an area of three or morefunctions (that is, when the user exists in an area where areas of threeor more functions overlap each other), the display of the conversationpartner is switched to the display of the three or more functions.Further, the display example illustrated in FIGS. 13A to 13E may beapplied to the eighth exemplary embodiment.

Modifications 3 and 4 may be applied to the eighth exemplary embodiment.That is, when the user exists in an area of plural functions, thecontrol unit 26 receives an execution instruction of linkage functionsexecutable using the plural functions, and when the user does not existin the area of the plural functions, the control unit 26 does notreceive any execution instruction of the linkage functions executableusing the plural functions.

Ninth Exemplary Embodiment

Hereinafter, a ninth exemplary embodiment will be described. The ninthexemplary embodiment corresponds to the combination of the fourthexemplary embodiment and the eighth exemplary embodiment. That is, whenthe user exists both in an area of a device and in an area of afunction, an image associated with a conversation partner is switched toa device image associated with the device and a function imageassociated with the function. Hereinafter, the ninth exemplaryembodiment will be described in detail.

FIG. 20 illustrates an exemplary linkage function management tableaccording to the ninth exemplary embodiment. The linkage functionmanagement table is information indicating linkage functions executableusing devices and functions (for example, software). In the linkagefunction management table, as an example, a combination of IDs (forexample, a combination of a device ID and a function ID), informationindicating device names and function names, and information indicatinglinkage functions executable using devices and functions are associatedwith each other. The linkage functions executable using devices andfunctions are specified by referring to the linkage function managementtable. For example, a linkage function of transmitting data using the PC(A) is implemented by combining, for example, the PC (A) as a device Awith the data transmission function as a function a. For other devicesand functions, executable linkage functions are similarly specified.

A linkage function executable using three or more devices and functionsmay be specified. In this case, a combination of three or more devicesand functions and a linkage function are associated with each other, andthe association is registered in the linkage function management table.

FIG. 21 illustrates a screen 56. The screen 56 displays an image 58associated with the automatic response AI and an image 60 associatedwith the user are displayed as in FIG. 8, and further displaysinformation indicating the conversation between the user and theautomatic response AI.

When the chatting program is activated, a message content 180 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

In the ninth exemplary embodiment, it is assumed that the user (theterminal device 10) exists in both an area of a multifunction device (B)and an area of a password function. In this case, the specifying unit 30identifies the multifunction device (B) as a device to be linked andidentifies the password function as a function to be linked. Thespecifying unit 30 specifies linkage functions associated with thecombination of the multifunction device (B) and the password function inthe linkage function management table illustrated in FIG. 20. Therefore,the linkage functions executable using the multifunction device (B) andthe password function are specified.

Further, since the user exists in both the area of the multifunctiondevice (B) and the area of the password function, the control unit 26displays the device image 66 associated with the multifunction device(B) and the function image 134 associated with the password function, inthe display area 56 a as images associated with the conversationpartner, in place of the image 58 associated with the automatic responseAI. The control unit 26 displays a message content 184 for confirmingthat the multifunction device (B) and the password function have beenidentified as objects to be linked in the display area 56 a as a messagecontent of the multifunction device (B) and the password function.

Further, when the user requests use of a device and a function by makinga message such as “I want to use the multifunction device (B) and thepassword function”, a character string indicating the request may bedisplayed as a message content 182 of the user in the display area 56 b.When the user inputs the message content 182 to the terminal device 10as described above, the specifying unit 30 may identify themultifunction device (B) and the password function as objects to belinked, and the control unit 26 may switch the image 58 associated withthe automatic response AI to the images 66 and 134.

When the user approves with respect to the message content 184 (forexample, when the user issues a message content 186 such as “Yes”), thecontrol unit 26 displays the information on the linkage functionsexecutable using the multifunction device (B) and the password functionin the display area 56 a as a message content 188 of the multifunctiondevice (B) and the password function. The message content 188 itself isa message content created by the general-purpose automatic response AI.The following process is the same as that of the seventh exemplaryembodiment described above.

For example, when the user gives an execution instruction of “a functionof setting a password to scanned data,” the control unit 26 gives theexecution instruction of scan transfer to the multifunction device (B).The multifunction device (B) scans according to the executioninstruction and transfers data thus generated to the terminal device 10.The control unit 26 activates password setting software and sets apassword to the data by the password setting software.

When the user (the terminal device 10) moves out of the area of themultifunction device (B) and the password function, the control unit 26displays the image 58 associated with the general-purpose automaticresponse AI in the display area 56 a as an image associated with theconversation partner, in place of the device image 66 and the functionimage 134.

When the user moves out of the area of the password function but existsin the area of the multifunction device (B), the control unit 26 maydisplay the device image 66 in the display area 56 a as an imageassociated with the conversation partner. In this case, the specifyingunit 30 identifies the multifunction device (B) as a device to be used.The same is true when the user moves out of the area of themultifunction device (B) but exists in the area of the passwordfunction.

As described above, according to the ninth exemplary embodiment, thedisplay of the conversation partner who is responding may be switched tothe display of the device and function to be linked. In this manner, theuser may visually confirm the conversation partner who is responding.

In the ninth exemplary embodiment, a stock area for a device image or astock area for a function image may be displayed in the display area 56b. In the above-described example, a device image associated with themultifunction device (B) is displayed in a stock area for the deviceimage, and a function image associated with the password function isdisplayed in a stock area for the function image. The user may selectthe device image and the function image from the respective stock areasand transmit the images to the automatic response AI as a messagecontent of the user. The specifying unit 30 identifies the deviceassociated with the device image and the function associated with thefunction image, which are selected by the user, as objects to be linked.When the user selects only one device image without selecting anyfunction image, the specifying unit 30 identifies the device associatedwith the device image as a device to be used. When the user selectsplural device images without selecting any function image, thespecifying unit 30 identifies the plural devices as devices to belinked. Similarly, when the user selects only one function image withoutselecting any device image, the specifying unit 30 identifies thefunction associated with the function image as a function to be used.When the user selects plural function images without selecting anydevice image, the specifying unit 30 identifies the plural functions asfunctions to be linked.

The conversation partner of the user may be a general-purpose automaticresponse AI equipped in the terminal device 10, or may be switched fromthe general-purpose automatic response AI to an automatic response AIassigned to each of the device and the function.

Modifications 1 to 4 may be applied to the ninth exemplary embodiment.

Tenth Exemplary Embodiment

Hereinafter, a tenth exemplary embodiment will be described. In thetenth exemplary embodiment, the display of the conversation partner isswitched to the display of a file (data) depending on the position ofthe user. For example, usable files change depending on the position ofthe user, and accordingly, the display of the conversation partner isswitched to the display of the file.

For example, management information indicating association between anarea and a usable file in the area is prepared in advance, and themanagement information is stored in the storage unit 24 of the terminaldevice 10. Of course, the management information may not be stored inthe terminal device 10 but may be stored in an external device such asthe server 16. The specifying unit 30 identifies the position of theterminal device 10 (the user) based on the position information of theterminal device 10 acquired by the position information acquiring unit28 and specifies a file associated with the area including the positionof the user in the management information. This file is a file that isusable by the terminal device 10 in the place where the user exists. Forexample, a file that is usable only in a specific office is determined,and the position of the specific office and the file are associated witheach other and registered in the management information. When the userexists in the specific office, the terminal device 10 is enabled to usethe file associated with the specific office. The file may be stored inthe terminal device 10 or may be stored in an external device such asthe server 16.

Here, the file will be described. Examples of the file include adocument file, an image file, a video file, a spreadsheet file, apresentation file, a graphic (figure) file, and an audio file.

The document file is a file having a document format, and is a fileconfigured with character strings and other pieces of information. Thedocument file may include images, tables, or figures as other pieces ofinformation. The document format is, for example, a text format or adocument format. The document file corresponds to, for example, datahaving a text format (for example, data appended with a character string“.txt” as an extension) or data having a document format (for example,data appended with a character string “.doc” or “.docx” as anextension).

The image file is a file having an image format. The image file may beimage data having a raster format or image data having a vector format.The image format is, for example, a JPEG format, a BMP (bitmap) format,a PDF format, a GIF format, a TIFF format, a PNG format, or a PICTformat. The image file corresponds to, for example, data having a JPEGformat (data appended with a character string “.jpeg” as an extension),data having a BMP format (data appended with a character string “.bmp”as an extension), data having a PDF format (data appended with acharacter string “.pdf” as an extension), data having a GIF format (dataappended with a character string “.gif” as an extension), data having aTIFF format (data appended with a character string “.tiff” as anextension), data having a PNG format (data appended with a characterstring “.png” as an extension), or data having a PICT format (dataappended with a character string “.pict” as an extension). Image fileshaving other formats may be used.

The video file is a file having a video format. The video format is, forexample, an AVI format, an MP4 format, an MOV format, an MPEG2-TSformat, an MPEG2-PS format, a WMV format, or an FLV format. The videofile corresponds to, for example, data having an AVI format (dataappended with a character string “.avi” as an extension), data having anMP4 format (data appended with a character string “.mp4” as anextension), data having an MOV format (data appended with a characterstring “.mov” as an extension), data having an MPEG2-TS format (dataappended with a character string “.m2ts” as an extension), data havingan MPEG2-PS format (data appended with a character string “.mpeg” as anextension), data having a WMV format (data appended with a characterstring “.wmv” as an extension), or data having an FLV format (dataappended with a character string “.flv” as an extension). Video fileshaving other formats may be used.

The spreadsheet file is a file having a table format and is configuredwith tables, graphs, or other pieces of information. The spreadsheetfile may include character strings, images, or figures as other piecesof information. For example, the spreadsheet file is data appended witha character string “.csv,” “.xls” or “.xlsx” as an extension.

The presentation file is a file having a presentation sheet format. Forexample, the presentation file corresponds to data appended with acharacter string “.ppt” or “.pptx” as an extension. The presentationfile is configured with, for example, character strings, images (stillimages or moving images), figures, and voice.

The graphic file is a file having a graphic (figure) format. The graphicfile is created by, for example, graphic generating software (forexample, two-dimensional CAD or three-dimensional CAD). For example, thegraphic file corresponds to data having a DXF format (data appended witha character string “.dxf” as an extension) or data having a DWG format(data appended with a character string “.dwg” as an extension). Inaddition, data appended with a character string “.vsd” or “.vsdx” as anextension may be treated as the graphic file.

The audio file is a file having an audio format. The audio format is,for example, an uncompressed audio format (for example, a WAV format, anAIFF format, or a BWF format), an irreversible compressed audio format(for example, an mp3 format, an AAC format, or a WMA format), or areversible compressed audio format (for example, a TAK format or an FLACformat). The audio file corresponds to data having an uncompressed audioformat (data appended with, for example, a character string “.wav” as anextension), data having an irreversible compressed audio format (dataappended with, for example, a character string “.mp3” as extension), ordata having an uncompressed audio format (data appended with, forexample, a character string “.tak” as an extension).

Hereinafter, the tenth exemplary embodiment will be described in detailwith reference to FIG. 22. FIG. 22 illustrates a screen 56. The screen56 displays an image 58 associated with the automatic response AI and animage 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 192 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

The position information acquiring unit 28 acquires position informationof the terminal device 10 (the user), and the specifying unit 30identifies the position of the terminal device 10 based on the positioninformation. For example, when the user exists in an area where adocument file A is usable, the specifying unit 30 determines that theuser (terminal device 10) exists in an area where the document file A isusable, based on the position information of the terminal device 10.

When the user (the terminal device 10) exists in an area where thedocument file A is usable, the specifying unit 30 identifies thedocument file A as a file to be used.

When the user (the terminal device 10) exists in an area of a file, thecontrol unit 26 switches the display of the conversation partner fromthe display of the general-purpose automatic response AI to the displayof the file (for example, an image associated with the file or acharacter string indicating the file).

In the above-described example, since the user exists in the area of thedocument file A, the control unit 26 displays a file image 196associated with the document file A in the display area 56 a as an imageassociated with the conversation partner, in place of the image 58associated with the automatic response AI. The file image is, forexample, an image such as an icon representing the file.

The control unit 26 may display a character string indicating thedocument file A in the display area 56 a as information indicating theconversation partner, in place of the file image 196 or along with thefile image 196.

Further, the control unit 26 displays a message content 198 such as “Doyou want to open the document file A?” in the display area 56 a as amessage content of the document file A. The message content 198 itselfis a message content created by the general-purpose automatic responseAI. The control unit 26 displays the message content 198 in the displayarea 56 a as a message content associated with the file image 196 of thedocument file A, in order to act as if the document file A makes themessage content 198.

Further, when the user requests use of a file by making a message suchas “I want to use the document file A”, a character string indicatingthe request may be displayed as a message content 194 of the user in thedisplay area 56 b.

When the user inputs the message content 194 to the terminal device 10as described above, the specifying unit 30 may identify the documentfile A as a file to be used, and the control unit 26 may switch theimage 58 associated with the automatic response AI to the file image 196associated with the document file A.

When the user instructs disclosure of the file (for example, when amessage content 200 such as “Yes” is input) with respect to the messagecontent 198 described above, the message content 200 is displayed in thedisplay area 56 b as the message content of the user.

Upon receiving the disclosure instruction, the control unit 26 displaysa message content 202 indicating that document software associated withthe document file A is activated, in the display area 56 a as a messagecontent of the automatic response AI. Further, the control unit 26activates the document software and causes the document software todisplay the document file A on the display unit of the UI unit 20. Forexample, the user may edit the document file A using the documentsoftware.

When the user (the terminal device 10) moves out of the area of thedocument file A, the control unit 26 displays the image 58 associatedwith the general-purpose automatic response AI in the display area 56 aas an image associated with the conversation partner, in place of thefile image 196 associated with the document file A.

As described above, according to the tenth exemplary embodiment, whenthe user (the terminal device 10) exists in an area of a file, the fileis identified as a file to be used, and the display of a conversationpartner who is responding is switched to the display of the file. Inthis manner, the user may visually confirm the conversation partner whois responding.

When an automatic response AI is assigned for each file, the display ofthe conversation partner may be switched from the display of thegeneral-purpose automatic response AI to the display of the file, andthe automatic response AI as a conversation partner for the user may beswitched from the general-purpose automatic response AI to an automaticresponse AI assigned to the file.

(Modification 5)

Hereinafter, Modification 5 will be described. In Modification 5, thecontrol unit 26 controls the output of an instruction related to a fileto the conversation partner who is responding, depending on the positionof the user. For example, when the user exists in the area of the file,the control unit 26 receives an instruction related to the file from theuser. Meanwhile, when the user exists outside the area of the file, thecontrol unit 26 does not receive an instruction related to the file fromthe user. In this manner, when the user exists in the area of the file,the user is able to give instructions to the file, and when the userexists outside the area of the file, the user is not able to giveinstructions to the file. Since the area where instructions are able tobe given to the file is limited, the security of the file may beimproved. For example, the security of the file may be improved bysetting the area of the file such that only users who stay in a specificroom in the office are able to give instructions to the file associatedwith the specific room.

For example, when the user exists in the area of the document file A,the control unit 26 receives a user's instruction related to thedocument file A. For example, the user may edit the document file Ausing the UI unit 20 of the terminal device 10. Meanwhile, when the userexists outside the area of the document file A, the control unit 26 doesnot receive a user's instruction related to the document file A. In thiscase, the user is unable to edit the document file A. The display of thedocument file A may be prohibited. In this manner, it is possible toconstruct a secure environment for the document file A.

In Modification 5, when the user exists in an area of a file, thecontrol unit 26 may or may not switch the image associated with theconversation partner from the image associated with the general-purposeautomatic response AI to an image associated with the file.

Eleventh Exemplary Embodiment

Hereinafter, an eleventh exemplary embodiment will be described withreference to FIG. 23. In the tenth exemplary embodiment, one file isidentified. In the eleventh exemplary embodiment, however, plural filesare identified.

FIG. 23 illustrates a screen 56. The screen 56 displays an image 58associated with the automatic response AI and an image 60 associatedwith the user are displayed as in FIG. 8, and further displaysinformation indicating the conversation between the user and theautomatic response AI.

When the chatting program is activated, a message content 204 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

The position information acquiring unit 28 acquires position informationof the terminal device 10, and the specifying unit 30 identifies theposition of the terminal device 10 based on the position information.

For example, it is assumed that the user exists in both of an area wherea document file A is usable and an area where an image file C is usable.That is, it is assumed that the user exists in an area where the area ofthe document file A and the area of the image file C overlap each other.In this case, the specifying unit 30 determines that the user (theterminal device 10) exists in the area where the document file A isusable, based on the position information of the terminal device 10.Further, the specifying unit 30 determines that the user (the terminaldevice 10) exists in the area where the image file C is usable, based onthe position information of the terminal device 10.

When the user (the terminal device 10) exists in the area of thedocument file A, the specifying unit 30 identifies the document file Aas a candidate of a file to be used. Similarly, when the user (theterminal device 10) exists in the area of the image file C, thespecifying unit 30 identifies the image file C as a candidate of a fileto be used.

When plural files are identified as described above, the control unit 26displays a stock area 206 in the display area 56 b for the user anddisplays file images in the stock area 206. The stock area 206 is anarea where information on candidates of a file to be used is displayed.In the example illustrated in FIG. 23, the file images are displayed asan example of candidate information. For example, the control unit 26displays the file images associated with the files identified asdescribed above in the stock area 206. In the example illustrated inFIG. 23, file images 208 and 210 are displayed in the stock area 206.The file image 208 is an image associated with the document file A. Thefile image 210 is an image associated with the image file C. When thefiles are identified in this manner, the control unit 26 displays fileimages associated with the files in the stock area 206. Of course, thecontrol unit 26 may display character information indicating theidentified files in the stock area 206, in place of the file images oralong with the file images.

When the user exists only in the area of the document file A, only thefile image 208 associated with the document file A is displayed in thestock area 206. Similarly, when the user exists only in the area of theimage file C, only the file image 210 associated with the image file Cis displayed in the stock area 206.

Further, when there are other file images that cannot be all displayedin the stock area 206, the user performs a scroll operation on the fileimages displayed in the stock area 206 such that the other file imagesare displayed in the stock area 206.

The user may select an image associated with the file to be used (thefile image 208 in the example illustrated in FIG. 23) from the stockarea 206 and move the file image 208 out of the stock area 206, so thatthe file image 208 may be transmitted to the automatic response AI as amessage content of the user. The user may input character information orvoice information indicating a file to be used to the terminal device 10so that information indicating the file to be used is transmitted to theautomatic response AI.

As described above, when a file to be used is designated by the user,the control unit 26 switches the display of the conversation partnerfrom the display of the general-purpose automatic response AI to thedisplay of the file. In the example illustrated in FIG. 23, since theuser designates the document file A as a file to be used by designatingthe file image 208, the control unit 26 displays the file image 196associated with the document file A in the display area 56 a as an imageassociated with the conversation partner, in place of the image 58associated with the automatic response AI.

Then, similarly to the tenth exemplary embodiment, the control unit 26displays a message content 212 such as “Do you want to open the documentfile A?” in the display area 56 a as a message content of the documentfile A.

When the user (the terminal device 10) moves out of the area of thedocument file A, the control unit 26 displays the image 58 associatedwith the general-purpose automatic response AI in the display area 56 aas an image associated with the conversation partner, in place of thefile image 196 associated with the document file A. Further, the controlunit 26 deletes the file image 208 associated with the document file Afrom the stock area 206. When the user (the terminal device 10) movesout of the area of the image file C, the control unit 26 deletes thefile image 210 associated with the image file C from the stock area 206.When the user moves into an area of a new file, the new file isidentified as a candidate of a file to be used, and information of thenew file (for example, a file image associated with the new file) isdisplayed in the stock area 206.

As described above, according to the eleventh exemplary embodiment, whenthe user (the terminal device 10) exists in an area of plural files, theplural files are identified as candidates of a file to be used, and thedisplay of a conversation partner who is responding is switched to thedisplay of a file selected from the plural files by the user. In thismanner, the user may visually confirm the conversation partner who isresponding.

The display of the conversation partner may be switched from the displayof the general-purpose automatic response AI to the display of the file,and the automatic response AI (for example, the program) as aconversation partner for the user may be switched from thegeneral-purpose automatic response AI to an automatic response AIassigned to the file.

When the user exists in the area of plural files, the specifying unit 30may identify a file closest to the user among the plural files as thefile to be used, and the control unit 26 may switch the display of thegeneral-purpose automatic response AI to the display of the file closestto the user.

(Modification 6)

Hereinafter, Modification 6 will be described. Similarly to Modification5, in Modification 6, the control unit 26 controls the output of aninstruction related to a file to the conversation partner who isresponding, depending on the position of the user. For example, when theuser exists in an area of plural files, the control unit 26 receives aninstruction related to each of the plural files from the user.

For example, when the user exists in both the area of the document fileA and the area of the image file C, the control unit 26 receives auser's instruction related to the document file A and the image file C.For example, the user may edit the document file A and the image file Cusing the UI unit 20 of the terminal device 10.

Further, when a file is selected from plural files by the user, thecontrol unit 26 may receive an instruction related to the selected filefrom the user. In the example illustrated in FIG. 23, the user exists inboth areas of the document file A and the image file C, but the documentfile A is selected by the user. In this case, the control unit 26receives a user's instruction related to the document file A.

Further, when the user exists in an area of plural files, the controlunit 26 may receive, from the user, an instruction related to a fileclosest to the user among the plural file.

According to Modification 6, when the user exists in an area of pluralfiles, it is possible to construct a secure environment for the files.

In Modification 6, when the user exists in an area of a file, thecontrol unit 26 may or may not switch the image associated with theconversation partner from the image associated with the general-purposeautomatic response AI to an image associated with the file.

Twelfth Exemplary Embodiment

Hereinafter, a twelfth exemplary embodiment will be described. In theeleventh exemplary embodiment, one file is selected by the user. In thetwelfth exemplary embodiment, however, plural files are selected by theuser.

The linkage function management information according to the twelfthexemplary embodiment is information for managing linkage functionsexecuted by linking plural functions to each other. The linkage functionis a function implemented by linking plural software to each other. Ofcourse, the linkage function may be a function implemented by linkingthe function that the device has as hardware and the functionimplemented by software to each other.

In the twelfth exemplary embodiment, the linkage function is a functionto be executed on plural files. For example, each file is associatedwith software (application) for executing a process on the file. Thelinkage function is a function implemented by linking applicationsassociated with each of the plural files selected by the user.

A linkage function is defined for each file format (attribute), and thelinkage function management information is, for example, informationindicating association between information indicating a combination ofplural file formats and information indicating a linkage function(linkage function information). The linkage function informationincludes, for example, a linkage function ID, a linkage function name,or the like. The file format is, for example, the above-describeddocument format, image format, video format, table format, sheet format,graphic format, or audio format. A linkage function compatible with acombination of the plural file formats is specified (identified) byreferring to the linkage function management information.

The linkage function may be a function implemented by linking pluraldifferent functions (for example, different pieces of software) to eachother or a function implemented by linking identical functions (forexample, identical pieces of software) to each other. The linkagefunction may be a function that is unusable before the linkage. Afunction which is unusable before the linkage may be a function whichbecomes usable by linking identical functions to each other, or afunction which becomes usable by combining different functions to eachother. For example, when a document creation function (document creationsoftware) and an image display function (image display software (forexample, an image viewer)) are linked to each other, a function ofinserting (attaching) an image into a document or a function ofsuperimposing a document (a character string or a text) on an image isimplemented as a linkage function. That is, an image insertion functionor a text superimposition function is implemented by linking thedocument creation function and the image display function to each other.

The linkage function managed by the linkage function managementinformation may be a function executable by software installed in theterminal device 10, a function executable by software installed in anexternal device (for example, a server or another terminal device), or afunction executable by software installed in the terminal device 10 andsoftware installed in an external device.

Hereinafter, the linkage function management information according tothe twelfth exemplary embodiment will be described in detail withreference to FIG. 24. FIG. 24 illustrates an exemplary linkage functionmanagement table according to the twelfth exemplary embodiment. In thelinkage function management table, as an example, information indicatinga combination of plural file formats and information indicating alinkage function (linkage function information) are associated with eachother. When plural files are identified as files to be linked, thespecifying unit 30 specifies a linking function associated with acombination of file formats of the plural files in the linkage functionmanagement table. Information on the linkage function is displayed onthe display unit of the UI unit 20. Although FIG. 24 illustrates acombination of two file formats, association between a combination ofthree or more file formats and a linkage function may be registered inthe linkage function management table.

Hereinafter, each linkage function illustrated in FIG. 24 will bedescribed.

In FIG. 24, the “document format” is a text format (with an extension of“.txt”) or a document format (with an extension of “.doc” or “.docx”).The “table format” is a format with an extension expressed as “.csv,”“.xls” or the like. The “image format” is a format with an extensionexpressed as “.jpeg,” “.pdf” or the like. The “video format” is a formatwith an extension expressed as, for example, “.avi,” “.mpeg” or thelike. The “sheet format” is a format with an extension expressed as“.ppt” or the like. While FIG. 24 does not illustrate the graphic formatand the audio format, association between a combination including thegraphic format and the audio format and a linkage function may beregistered in the linkage function management table. Of course,association between a combination including file formats other than thefile formats illustrated in FIG. 24 and a linkage function may be setand registered in the linkage function management table.

Hereinafter, each linkage function illustrated in FIG. 24 will bedescribed. When a document file A and a spreadsheet file B areidentified as files to be linked, a “function of inserting a table intoa document” and a “function of inserting a document into a table” whichare associated with a combination of the document format and the tableformat are specified as linkage functions. The “function of inserting atable into a document” is a function of inserting the table representedby the spreadsheet file B into the document represented by the documentfile A. The “function of inserting a document into a table” is afunction of inserting the document represented by the document file Ainto the table represented by the spreadsheet file B.

When a document file A and an image file C are identified as files to belinked, a “function of inserting an image into a document” and a“function of superimposing a document on an image” which are associatedwith a combination of the document format and the image format arespecified as linkage functions. The “function of inserting an image intoa document” is a function of inserting the image represented by theimage file C into the document represented by the document file A. The“function of superimposing a document on an image” is a function ofsuperimposing the document represented by the document file A on theimage represented by the image file C.

When a document file A and a video file D are identified as files to belinked, a “function of inserting a video into a document” and a“function of inserting a still image into a document” which areassociated with a combination of the document format and the videoformat are specified as linkage functions. The “function of inserting avideo into a document” is a function to insert the video represented bythe video file D into the document represented by the document file A.The “function of inserting a still image into a document” is a functionof inserting one or more frames (still images) included in the videofile D into the document represented by the document file A. Forexample, when the “function of inserting a still image into a document”is executed in a case where the document file A is a document file whichis not compatible with a video, that is, a file into which a videocannot be inserted, one or more frames (still images) included in thevideo file D are inserted into the document represented by the documentfile A.

Plural files having the same file format may be identified as files tobe linked. For example, when document files A1 and A2 are identified asfiles to be linked, a “function of integrating documents” which isassociated with the combination of the document format and the documentformat is specified as a linkage function. The “function of integratingdocuments” is a function of integrating the documents represented by thedocument files A1 and A2 with each other (for example, combining the twodocuments with each other) to generate a new document file A3 whilesaving or removing the document files A1 and A2.

When spreadsheet files B1 and B2 are identified as files to be linked, a“function of integrating tables” which is associated with thecombination of the table format and the table format is specified as alinkage function. The “function of integrating tables” is a function ofintegrating the tables represented by the spreadsheet files B1 and B2with each other (for example, combining the two tables with each other)to generate a new spreadsheet file B3 while saving or removing thespreadsheet files B1 and B2.

When video files D1 and D2 are identified as files to be linked, a“function of integrating videos” which is associated with thecombination of the video format and the video format is specified as alinkage function. The “function of integrating tables” is a function ofintegrating the videos represented by the video files D1 and D2 witheach other (for example, combining the two videos with each other) togenerate a new video file D3 while saving or removing the video files D1and D2.

In addition, when a presentation file E and the document file A areidentified as files to be linked, a “function of inserting a documentinto a presentation sheet” which is associated with the combination ofthe sheet format and the document format is specified as a linkagefunction. The “function of inserting a document into a presentationsheet” is a function of inserting the document represented by thedocument file A into the presentation sheet represented by thepresentation file E.

A linkage function associated with three or more files may be registeredin the linkage function management table.

In the linkage function management table, combinations of file names anda linkage function may be associated with each other. When plural filesare identified as files to be linked, the specifying unit 30 specifies alinkage function associated with a combination of plural file names inthe linkage function management table.

Further, the specifying unit 30 may specify a file to which a content tobe added, based on a name of a file transmitted to the automaticresponse AI. For example, when a name of a file (file name) includes acharacter string suggesting a file for collecting data (that is, a fileassumed or predicted to incorporate a content of other data), such as“ledger,” “collection,” “management,” “statistics,” “graph,” “table,” or“list,” the specifying unit 30 identifies the file as a file to whichthe content is to be added. Further, the specifying unit 30 identifies afile having a file name including no character string for the collectionor a file having a file name including a character string suggesting afile for providing a content (material), as a file containing a content(material) to be added. For example, a file having a file name includinga character string such as “receipt,” “slip,” “personal data,” or“device data” does not correspond to the file for the collectiondescribed above and is determined to correspond to a file for providinga content (material).

FIG. 25 illustrates a screen 56. The screen 56 displays an image 58associated with the automatic response AI and an image 60 associatedwith the user are displayed as in FIG. 8, and further displaysinformation indicating the conversation between the user and theautomatic response AI.

When the chatting program is activated, a message content 214 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

In the twelfth exemplary embodiment, similarly to the eleventh exemplaryembodiment described above, it is assumed that the user (the terminaldevice 10) exists in both an area of a document file A and an area of animage file C. In this case, a file image 208 associated with thedocument file A and a file image 210 associated with the image file Care displayed in the stock area 206.

For example, the user may select the file images 208 and 210 from thestock area 206 and move the file images 208 and 210 out of the stockarea 206, so that the file images 208 and 210 may be transmitted to theautomatic response AI as a message content of the user. In the exampleillustrated in FIG. 25, an image 216 in which the file images 208 and210 are displayed is generated, and the image 216 is transmitted to theautomatic response AI. The user may input character information or voiceinformation indicating plural files to be used to the terminal device 10so that information indicating the plural files to be used istransmitted to the automatic response AI.

As described above, when plural files to be used are designated by theuser, the specifying unit 30 identifies the plural files as files to belinked and specifies linkage functions associated with a combination ofthe plural files, for example, in the linkage function management tableillustrated in FIG. 24. Therefore, the linkage functions executableusing the plural files are identified.

In the above-described example, the specifying unit 30 identifies thedocument file A associated with the file image 208 and the image file Cassociated with the file image 210 as files to be linked and specifieslinkage functions (for example, a “function of inserting an image into adocument” and a “function of superimposing a document on an image”)associated with the combination of the document format and the imageformat in the linkage function management table illustrated in FIG. 24.Therefore, the linkage functions executable for the document file A andthe image file C are identified. The process of specifying the files andthe linkage functions may be performed by the server 16.

Further, when plural files to be used are designated by the user, thecontrol unit 26 switches the display of the conversation partner fromthe display of the general-purpose automatic response AI to the displayof the plural files designated by the user.

In the above-described example, since the document file A and the imagefile C are designated as files to be linked, the control unit 26displays the file image 196 associated with the document file A and thefile image 218 associated with the image file C in the display area 56 aas images associated with the conversation partner, in place of theimage 58 associated with the automatic response AI. Of course, thecontrol unit 26 may display a character string indicating the documentfile A and the image file C in the display area 56 a as informationindicating the conversation partner, in place of the file images 196 and218 or along with the file images 196 and 218.

Further, the control unit 26 displays a message content 220 forconfirming the plural files designated by the user in the display area56 a as a message content of the automatic response AI. In the casewhere the document file A and the image file C are designated as thefiles to be linked, for example, a message content 220 such as “Documentfile A and Image file C?” is displayed as a message content of theautomatic response AI in the display area 56 a.

When the user approves with respect to the message content 220 (forexample, when the user issues a message content 222 such as “Yes”), thecontrol unit 26 displays the information on the linkage functionsexecutable using the document file A and the image file C in the displayarea 56 a as a message content 224 of the document file A and the imagefile C. The message content 224 itself is a message content created bythe general-purpose automatic response AI. The control unit 26 displaysthe message content 224 in the display area 56 a as a message contentassociated with the file image 196 of the document file A and the fileimage 218 of the image file C, in order to act as if the document file Aand the image file C make the message content 224.

When the user gives an execution instruction with respect to the messagecontent 224 by designating linkage functions by a message content 226,the control unit 26 receives the execution instruction and controls theexecution of the linkage functions. As another example, a button imagefor instructing the execution of the linkage functions is displayed onthe screen 56, and the user may press the button image to give anexecution instruction of the linkage functions. For example, when the“function of inserting an image into a document” is designated by theuser, the control unit 26 activates document software and image softwareto inserts the image file C into the document file A.

When the user (the terminal device 10) moves out of the area of thedocument file A and the image file C, the control unit 26 displays theimage 58 associated with the general-purpose automatic response AI inthe display area 56 a as an image associated with the conversationpartner, in place of the file images 196 and 218. Further, the controlunit 26 deletes the file image 208 associated with the document file Aand the file image 210 associated with the image file C from the stockarea 206.

When the user moves out of the area of the document file A but exists inthe area of the image file C, the control unit 26 may display the fileimage 218 in the display area 56 a as an image associated with theconversation partner. In this case, the specifying unit 30 identifiesthe image file C as a file to be used. The same is true when the usermoves out of the area of the image file C but exists in the area of thedocument file A.

As described above, according to the twelfth exemplary embodiment, thedisplay of the conversation partner who is responding may be switched tothe display of the plural files to be linked. In this manner, the usermay visually confirm the conversation partner who is responding.

When plural files are displayed as conversation partners, theconversation partner of the user may be a general-purpose automaticresponse AI equipped in the terminal device 10, or may be switched fromthe general-purpose automatic response AI to an automatic response AIassigned to each of the plural files.

In the example illustrated in FIG. 25, information of two files istransmitted to the automatic response AI, but information of three ormore files (for example, three or more file images or character stringsindicating three or more files) may be transmitted to the automaticresponse AI. In this case, in place of the image 58 associated with theautomatic response AI, three or more file images are displayed as imagesassociated with the conversation partners in the display area 56 a.Further, the display example illustrated in FIGS. 13A to 13E may beapplied to the twelfth exemplary embodiment.

Modifications 5 and 6 may be applied to the twelfth exemplaryembodiment. That is, when the user exists in an area of plural files,the control unit 26 receives an execution instruction of linkagefunctions executable using the plural files, and when the user does notexist in the area of the plural files, the control unit 26 does notreceive any execution instruction of the linkage functions executableusing the plural files.

Thirteenth Exemplary Embodiment

Hereinafter, a thirteenth exemplary embodiment will be described withreference to FIG. 26. FIG. 26 illustrates a screen 56. The screen 56displays an image 58 associated with the automatic response AI and animage 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 228 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

In the thirteenth exemplary embodiment, similarly to the twelfthexemplary embodiment described above, it is assumed that the user (theterminal device 10) exists in both an area of a document file A and anarea of an image file C. In this case, the specifying unit 30 identifiesthe document file A and image file C as files to be linked and specifieslinkage functions associated with the combination of the document file Aand the image file C, for example, in the linkage function managementtable illustrated in FIG. 24. Therefore, the linkage functionsexecutable for the document file A and the image file C are identified.

Further, since the user exists in both areas of the document file A andthe image file C, the control unit 26 displays the file image 196associated with the document file A and the file image 218 associatedwith the image file C in the display area 56 a as images associated withthe conversation partner, in place of the image 58 associated with theautomatic response AI. The control unit 26 displays a message content232 for confirming that the document file A and the image file C havebeen identified as files to be linked in the display area 56 a as amessage content of the document file A and the image file C.

Further, when the user requests use of a file by making a message suchas “I want to use the document file A and the image file C”, a characterstring indicating the request may be displayed as a message content 230of the user in the display area 56 b. When the user inputs the messagecontent 230 to the terminal device 10 as described above, the specifyingunit 30 may identify the document file A and the image file C as filesto be linked, and the control unit 26 may switch the image 58 associatedwith the automatic response AI to the file images 196 and 218.

When the user approves with respect to the message content 232 (forexample, when the user issues a message content 234 such as “Yes”), thecontrol unit 26 displays the information on the linkage functionsexecutable using the document file A and the image file C in the displayarea 56 a as a message content 236 of the document file A and the imagefile C. The message content 236 itself is a message content created bythe general-purpose automatic response AI. A linkage function to beexecuted is designated by the message content 238 of the user. Thefollowing process is the same as that of the twelfth exemplaryembodiment described above.

As described above, according to the thirteenth exemplary embodiment,when a user exists in an area of plural files, the display of theconversation partner who is responding is switched to the display of theplural files. In this manner, the user may visually confirm theconversation partner who is responding.

The conversation partner may be switched from the general-purposeautomatic response AI to an automatic response AI of the plural files.Further, when the user exists in an area of three or more files (thatis, when the user exists in an area where areas of three or more filesoverlap each other), the display of the conversation partner is switchedto the display of the three or more files. Further, the display exampleillustrated in FIGS. 13A to 13E may be applied to the thirteenthexemplary embodiment.

Modifications 5 and 6 may be applied to the thirteenth exemplaryembodiment. That is, when the user exists in an area of plural files,the control unit 26 receives an execution instruction of linkagefunctions executable using the plural files, and when the user does notexist in the area of the plural files, the control unit 26 does notreceive any execution instruction of the linkage functions executableusing the plural files.

Fourteenth Exemplary Embodiment

Hereinafter, a fourteenth exemplary embodiment will be described. In thefourteenth exemplary embodiment, the message content of the automaticresponse AI changes depending on the position of the user. The messagecontent of the automatic response AI may be changed depending on theposition of the user, and the display of the conversation partner may beswitched from the display of the general-purpose automatic response AIto the display depending on the position of the user.

For example, management information indicating association between anarea and contents provided to the terminal device 10 in the area isprepared in advance, and the management information is stored in thestorage unit 24 of the terminal device 10. Of course, the managementinformation may be stored in an external device such as the server 16.In this case, the management information may not be stored in theterminal device 10. Examples of the contents include characterinformation, voice information, image data (still image data or videodata), and the like. The contents are, for example, information relatedto a place. The information related to a place may be informationrelated to the place itself or may be information on a person relatingto the place. Information related to a place itself includes, forexample, information on a place name, map information, touristinformation (for example, information on sightseeing spots), shoppinginformation, information on facilities (shops, accommodations, publicfacilities, etc.), information on famous products, information onindustry, information on traffic guidance, weather information,information on an event occurred at the place (for example, informationon a historical incident or the like), and the like. Information on aperson is, for example, information on a historical figure (such as agreat person or a famous person). The data of the contents may be storedin the storage unit 24 of the terminal device 10 or may be stored in anexternal device such as the server 16. When the contents are stored inthe external device, the terminal device 10 acquires data of thecontents from the external device and provides the data to the user. Thespecifying unit 30 receives the position information of the user (theterminal device 10) and specifies contents associated with an areaincluding the position of the user in the management information. Thecontents are contents provided to the terminal device 10 at the placewhere the user is located. For example, contents are prepared for eacharea, and the contents for each area is provided.

Further, the management information may be information indicating theassociation between information of an area and a conversation partnerdisplayed on the terminal device 10 in the area, and contents providedto the terminal device 10 at the position. The specifying unit 30receives the position information of the user and specifies aconversation partner and contents associated with an area including theposition of the user in the management information. The control unit 26provides the contents to the user and switches the display of theconversation partner from the display of the general-purpose automaticresponse AI to the display of a conversation partner associated with theposition of the user.

Hereinafter, the fourteenth exemplary embodiment will be described indetail with reference to FIG. 27. FIG. 27 illustrates a screen 56. Thescreen 56 displays an image 58 associated with the automatic response AIand an image 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 240 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

The position information acquiring unit 28 acquires position informationof the terminal device 10 (the user), and the specifying unit 30identifies the position of the terminal device 10 based on the positioninformation and specifies the contents and the conversation partnerassociated with the area including the position in the managementinformation.

For example, when the user exists in an area U, the specifying unit 30specifies the contents and the conversation partner associated with thearea U in the above-described management information. It is assumed thatthe area U is associated with information on a great person Y as awriter as contents information, and a person image associated with thegreat person Y as an image associated with the conversation partner. Inthis case, the control unit 26 switches the display of the conversationpartner from the display of the general-purpose automatic response AI tothe display of the great person Y (for example, a person imageassociated with the great person Y or a character string indicating thegreat person Y). Further, the control unit 26 provides contents. Thegreat person Y corresponds to an example of the “partner.”

In the example illustrated in FIG. 27, the control unit 26 displays aperson image 242 associated with the great person Y in the display area56 a as an image associated with the conversation partner, in place ofthe image 58 associated with the general-purpose automatic response AI.The person image may be a picture or a moving image representing aperson, or a still image or a moving image schematically representingthe person.

The control unit 26 may display a character string indicating the greatperson Y in the display area 56 a as information indicating theconversation partner, in place of the person image 242 or along with theperson image 242.

Further, the control unit 26 displays, as contents related to the greatperson Y, a message content 244 such as “Have you read my book?” in thedisplay area 56 a as a message content of the great person Y. Further,as contents related to the great person Y, a work such as a novel may beprovided to the user via the terminal device 10.

Further, when the user exists in an area V, the specifying unit 30specifies the contents and the conversation partner associated with thearea V in the above-described management information. It is assumed thatthe area V is associated with information on a commercial facility Z ascontents information, and a building image associated with thecommercial facility Z as an image associated with the conversationpartner. In this case, the control unit 26 switches the display of theconversation partner from the display of the general-purpose automaticresponse AI to the display of the commercial facility Z (for example, abuilding image associated with the commercial facility Z or a characterstring indicating the commercial facility Z). Further, the control unit26 provides contents. The commercial facility Z corresponds to anexample of the “partner.”

In the example illustrated in FIG. 27, the control unit 26 displays abuilding image 246 associated with the commercial facility Z in thedisplay area 56 a as an image associated with the conversation partner,in place of the image 58 associated with the automatic response AI. Thebuilding image may be a picture or a moving image representing abuilding such as a facility, or a still image or a moving imageschematically representing the building.

The control unit 26 may display a character string indicating thecommercial facility Z in the display area 56 a as information indicatingthe conversation partner, in place of the building image 246 or alongwith the building image 246.

Further, the control unit 26 displays a message content 248 such as“Welcome to AAA (the name of the commercial facility Z)” as contentsrelated to the commercial facility Z, in the display area 56 a as amessage content of the commercial facility Z. Further, as contentsrelated to the commercial facility Z, service and shopping informationprovided at the commercial facility Z may be provided to the user viathe terminal device 10.

Further, the control unit 26 may change the expression of the messagecontent of the automatic response AI without switching the display ofthe conversation partner depending on the position of the user. Forexample, a language or a dialect is associated with each area, and thecontrol unit 26 expresses the message content of the automatic responseAI using the language or the dialect associated with the area includingthe position of the user. For example, when the user is in the Kansaiarea, the control unit 26 displays a message content 250 expressed bythe Kansai dialect in the display area 56 a as a message content of theautomatic response AI. Further, when the user is in an English speakingarea, the control unit 26 displays a message content expressed inEnglish in the display area 56 a as a message content of the automaticresponse AI.

As described above, according to the fourteenth exemplary embodiment,the message content of the conversation partner is changed depending onthe position of the user. As a result, information corresponding to theposition of the user is provided to the user. Further, the display ofthe conversation partner who is responding is switched depending on theposition of the user. In this manner, the user may visually confirm theconversation partner who is responding.

When the fourteenth exemplary embodiment is applied to, for example, atourist information service, regional information on sightseeing and thelike is provided to the user.

The fourteenth exemplary embodiment is not limited to the above example,but may be applied to a game or the like using the position of the user.For example, information on a character or an item depending on theposition of the user may be provided to the user as contentsinformation, or an image associated with the character or the item maybe displayed as an image associated with the conversation partner.

Fifteenth Exemplary Embodiment

Hereinafter, a fifteenth exemplary embodiment will be described. In thefifteenth exemplary embodiment, similarly to the fourteenth exemplaryembodiment described above, the message content of the automaticresponse AI is changed depending on the position of the user, and thedisplay of the conversation partner is switched from the display of theautomatic response AI to the display according to the position of theuser. The process according to the fifteenth exemplary embodiment is aprocess applied when the user exists in plural areas.

Hereinafter, the fifteenth exemplary embodiment will be described indetail with reference to FIG. 28. FIG. 28 illustrates a screen 56. Thescreen 56 displays an image 58 associated with the automatic response AIand an image 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 252 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

The position information acquiring unit 28 acquires position informationof the terminal device 10 (the user), and the specifying unit 30identifies the position of the terminal device 10 based on the positioninformation and specifies the contents and the conversation partnerassociated with the area including the position in the managementinformation according to the fourteenth exemplary embodiment.

For example, when the user exists in areas U and V (that is, when theuser exists in an area where the area U and the area V overlap eachother), the specifying unit 30 specifies the contents and theconversation partner associated with the area U and also specifies thecontents and the conversation partner associated with the area V, in theabove-described management information according to the fourteenthexemplary embodiment.

Similarly to the fourteenth exemplary embodiment, information on thegreat person Y is associated with the area U, and information on thecommercial facility Z is associated with the area V. In this case, thecontrol unit 26 switches the display of the conversation partner fromthe display of the general-purpose automatic response AI to the displayof the great person Y and the commercial facility Z.

In the example illustrated in FIG. 28, the control unit 26 displays aperson image 242 associated with the great person Y and a building image246 associated with the commercial facility Z, in the display area 56 aas images associated with the conversation partner, in place of theimage 58 associated with the automatic response AI.

Further, the control unit 26 displays a message content 254 as contentsrelating to the great person Y in the display area 56 a as a messagecontent of the great person Y and displays a message content 256 ascontents relating to the commercial facility Z in the display area 56 aas a message content of the commercial facility Z.

The display example illustrated in FIGS. 13A to 13E may also be appliedto the fifteenth exemplary embodiment. Further, the control unit 26 maydetermine the priority order of each partner (for example, the greatperson Y or the commercial facility Z) based on famousness, evaluation,access number, etc. of the partners, and change the display order andsize of the image associated with the partner according to the priorityorder of the partner. The control unit 26 acquires information such asfamousness, evaluation, access number, etc. of each partner using, forexample, the Internet, social network service (SNS), or the like, anddetermines the priority order of each partner. For example, the controlunit 26 may display an image associated with the higher-priority partneras being enlarged, or display images associated with the respectivepartners in the order of priority. For example, the control unit 26 maydisplay an image associated with a partner closer to the user in anenlarged manner, or may display images associated with respectivepartners in the order of closeness to the user.

Sixteenth Exemplary Embodiment

Hereinafter, a sixteenth exemplary embodiment will be described. In thesixteenth exemplary embodiment, when device identification informationis acquired to identify a device, the control unit 26 switches thedisplay of the conversation partner from the display of thegeneral-purpose automatic response AI to the display of the device.Further, the control unit 26 receives an instruction related to thedevice from the user.

The device identification information is, for example, code informationfor identifying the device or an external appearance image representingthe external appearance of the device. For example, when applying anaugmented reality (AR) technology, the device identification informationis acquired so that the device is identified. For example, by applyingthe AR technology, the device identification information of the deviceused alone is acquired, so that the device is identified, and the deviceidentification information of the device to be linked is acquired, sothat the device to be linked is identified. As the AR technology, anyknown AR technology is used. Examples thereof include a marker ARtechnique using a marker such as a two-dimensional barcode, a markerlessAR technique using an image recognition technology, a positioninformation AR technique using position information, and the like. Ofcourse, the device identification information may be acquired withoutusing the AR technology, and then the device may be identified. Forexample, when the device is connected to the network, the device may beidentified based on the IP address, or the device ID may be read toidentify the device. Further, in a case of using a device or a terminaldevice having various wireless communication functions such as infraredcommunication, visible light communication, Wi-Fi, Bluetooth, etc., theID of the device may be acquired using the wireless communicationfunction, so that the device is identified.

Hereinafter, the process of acquiring the device identificationinformation will be described in detail with reference to FIG. 29. As anexample, a case of acquiring the device identification information ofthe image forming device 12 will be described. FIG. 29 schematicallyillustrates the external appearance of the image forming device 12.Here, a process for acquiring device identification information byapplying the marker AR technique will be described. A marker 258 such asa two-dimensional barcode or the like is provided on the casing of theimage forming device 12. The marker 258 is information in which thedevice identification information of the image forming device 12 isencoded. A user activates the camera 22 of the terminal device 10 andcaptures the marker 258 provided in the image forming device 12 to beused with the camera 22. As a result, image data representing the marker258 is generated. The control unit 26 of the terminal device 10 extractsthe device identification information by applying a decoding process tothe marker image represented in the image data. As a result, the imageforming device 12 to be used (the image forming device 12 having thecaptured marker 258) is identified. The specifying unit 30 of theterminal device 10 specifies the function information indicating thefunction associated with the extracted device identification informationin the device function management information. Therefore, the functionthat the image forming device 12 to be used has is specified(identified). The decoding process may be performed by an externaldevice such as the server 16.

Function information indicating the functions that the image formingdevice 12 has may be encoded and included in the marker 258. In thiscase, when the decoding process is applied to the image datarepresenting the marker 258, the device identification information ofthe image forming device 12 is extracted, and the function informationindicating the function that the image forming device 12 has isextracted as well. As a result, the image forming device 12 is specified(identified), and functions that the image forming device 12 has arespecified (identified). The decoding process may be performed by theterminal device 10 or may be performed by the server 16.

Further, the device identification information of each of plural devicesis acquired by capturing a marker of each of the plural devices.

In a case of acquiring the device identification information by applyingthe markerless AR technique, for example, the user captures the entiretyor a part of the external appearance of the device to be used (forexample, the image forming device 12) by the camera 22 of the terminaldevice 10. Of course, it is useful to acquire information for specifyingdevices such as the name (for example, product name) of a device to beused, a model number, or an asset management number, by capturing theexternal appearance. External appearance image data representing theentirety or a part of the external appearance of the device to be usedis generated by image capturing. The control unit 26 of the terminaldevice 10 identifies the device to be used based on the externalappearance image data. For example, the storage unit 24 of the terminaldevice 10 stores, for each device, external appearance image associationinformation indicating the association between the external appearanceimage data representing the entirety or a part of the externalappearance of the device and the device identification information ofthe device. For example, the control unit 26 compares the externalappearance image data with each external appearance image data includedin the external appearance image association information, and specifiesthe device identification information of the device to be used based onthe comparison result. For example, the control unit 26 extractsfeatures of the external appearance of the device to be used from theappearance image data, specifies the external appearance image datarepresenting the same or similar features as the features of theexternal appearance in the external appearance image data group includedin the external appearance image association information, and specifiesthe device identification information associated with the externalappearance image data. As a result, the device to be used (the devicecaptured by the camera 22) is identified. As another example, when thename (for example, product name) or model number of the device iscaptured and external appearance image data representing the name ormodel number is generated, the device to be used may be identified basedon the name or model number indicated in the external appearance imagedata. The specifying unit 30 of the terminal device 10 specifies thefunction information indicating the functions associated with thespecified device identification information in the device functionmanagement information. Therefore, the functions that the device to beused (for example, the image forming device 12) has are specified. Anexternal device such as the server 16 may specify the deviceidentification information of the device based on the externalappearance image data.

The device identification information of each of plural devices isacquired by capturing the entirety or a part of the external appearanceof each of the plural devices.

When acquiring the device identification information by applying theposition information AR technique, position information indicating theposition where the device (for example, the image forming device 12) isinstalled is acquired by using, for example, the GPS function. Forexample, each device has the GPS function and acquires device positioninformation indicating the position of the device itself. The terminaldevice 10 outputs information indicating a device position informationacquisition request to the device to be used, and receives deviceposition information of the device from the device as a response to theacquisition request. The control unit 26 of the terminal device 10identifies the device to be used based on the device positioninformation. For example, the storage unit 24 of the terminal device 10stores, for each device, position association information indicating theassociation between the device position information indicating theposition where the device is installed and the device identificationinformation of the device. The control unit 26 specifies the deviceidentification information associated with the device positioninformation in the position association information. Therefore, thedevice to be used is specified (identified). The specifying unit 30 ofthe terminal device 10 specifies the function information indicating thefunctions associated with the specified device identificationinformation in the device function management information. Therefore,the function that the device to be used (for example, the image formingapparatus 12) has is specified (identified). An external device such asthe server 16 may specify the device based on the device positioninformation.

Device position information of each of plural devices is acquired, anddevice identification information of each device is specified based oneach piece of the device position information.

Plural identification techniques may be used to identify devices. Forexample, a device may be identified using plural techniques selectedfrom the marker AR technique, the markerless AR technique, and theposition information AR technique. Further, when a device cannot beidentified by a certain identification technique, the device may beidentified using another identification technique. For example, when adevice cannot be identified by the marker AR technique or the markerlessAR technique, the device may be identified using the positioninformation AR technique.

When respective devices are identified by the marker AR technique or themarkerless AR technique, each device may be captured separately andidentified, or may be captured together and identified. For example, themultifunction device (B) is captured in a state where the multifunctiondevice (B) is included in the image capturing area of the camera 22, andthen, the PC (A) is captured in a state where the PC (A) is included inthe image capturing area of the camera 22, so that the multifunctiondevice (B) and the PC (A) are sequentially identified. It is notnecessary that the respective devices to be linked are arranged close toeach other and both the multifunction device (B) and the PC (A) areincluded together in the capturing area of the camera 22. Thiscircumstance may be coped with by, for example, changing the angle ofthe capturing area, or enlarging or reducing the capturing area.However, there may be cases where such operation may not cope with thecircumstance. In this case, the respective devices are identified bycapturing the devices plural times.

For example, when the user captures the marker 258 of the image formingdevice 12 with the camera 22 after the automatic response AI issues acommon message content such as “How can I help You?” on the screen 56,the specifying unit 30 reads the device identification information fromthe marker 258 by applying the marker AR technique, and identifies theimage forming device 12. When the image forming device 12 is identified,the control unit 26 switches the image associated with the conversationpartner from the image 58 of the general-purpose automatic response AIto the device image associated with the image forming device 12.Further, the control unit 26 receives an instruction related to theimage forming device 12 from the user. In the case where the deviceidentification information is read so that the device is identified, forexample as in the example illustrated in FIG. 8, the message content 68is displayed in the display area 56 a. Further, when the user inputs themessage content 70, the control unit 26 receives the message content 70.That is, when the device identification information is acquired and thedevice is identified, the control unit 26 receives the message contentof the user with respect to the device. Thereafter, printing isperformed, and the message content 72 is displayed in the display area56 a.

Meanwhile, in a case where the marker 258 is not captured and the deviceidentification information is not read from the marker 258, the controlunit 26 displays the image 58 associated with the general-purposeautomatic response AI in the display area 56 a as an image associatedwith the conversation partner without switching the image associatedwith the conversation partner, and does not receive an instructionrelated to the image forming device 12 from the user. In the exampleillustrated in FIG. 8, the message contents 68 and 72 are not displayed,and even though the user inputs the message content 70 into the terminaldevice 10, the control unit 26 does not receive the message content 70.A common message content such as “How can I help you?” is displayed as amessage content of the automatic response AI.

Even when the markerless AR technique or the position information ARtechnique is used, the same process as in the case where the marker ARtechnique is used is performed.

As described above, according to the sixteenth exemplary embodiment,when the device identification information of the device is read, thedisplay of the conversation partner is switched from the display of theautomatic response AI to the display of the device, and an instructionwith respect to the device is received. In this manner, the user mayvisually confirm the conversation partner who is responding, and asecure environment for the device is constructed.

Further, by using the marker AR technique or the markerless ARtechnique, it is possible to identify and use the device even when theposition information of the device cannot be acquired.

The sixteenth exemplary embodiment may be applied to the case where alinkage function is executed. That is, when the device identificationinformation of each of plural devices is read, the display of theconversation partner is switched from the display of the automaticresponse AI to the display of the plural devices, and an instructionrelated to a linkage function executable using the plural devices isreceived. In this manner, the user may visually confirm the conversationpartner who is responding even when a linkage function is executed, anda secure environment for the plural devices is constructed.

The same process as described above may be performed when usingfunctions that the device has, software installed in the device, orfiles stored in the device. That is, when the device identificationinformation of the device is read and the device is identified, it ispossible to use the function that the device has, the software installedin the device, and the files stored in the device. Meanwhile, when thedevice identification information of the device is not read and thedevice is not identified, the use of the functions, the software, or thefiles is prohibited.

Seventeenth Exemplary Embodiment

Hereinafter, a seventeenth exemplary embodiment will be described. Inthe seventeenth exemplary embodiment, the control unit 26 acquiresinformation indicating the state of the device (status information), andswitches the display of the conversation partner who is responding fromthe display of the general-purpose automatic response AI to the displayof the device in which the state is reflected.

Hereinafter, the seventeenth exemplary embodiment will be described indetail with reference to FIG. 30. FIG. 30 illustrates a screen 56. Thescreen 56 displays an image 58 associated with the automatic response AIand an image 60 associated with the user are displayed as in FIG. 8, andfurther displays information indicating the conversation between theuser and the automatic response AI.

When the chatting program is activated, a message content 260 such as“How can I help you?” is displayed as a message content of the automaticresponse AI in the display area 56 a.

For example, it is assumed that the user gives an instruction to use themultifunction device (B) to the automatic response AI by inputting amessage content 262 such as “I want to use the multifunction device (B)”to the terminal device 10. The control unit 26 transmits the messagecontent 262 to the automatic response AI.

Upon receiving the message content 262, the control unit 26 acquiresinformation indicating the state of the multifunction device (B) (statusinformation) from the multifunction device (B). Of course, when thestate of the device is managed by an external device such as the server16 or the like, the control unit 26 may acquire the status informationof the multifunction device (B) from the external device.

For example, in a case where no paper is accommodated in themultifunction device (B), the status information of the multifunctiondevice (B) includes information indicating the status.

The control unit 26 identifies the state of the multifunction device (B)by analyzing the status information of the multifunction device (B). Forexample, in a case where the status information of the multifunctiondevice (B) includes information indicating that no paper isaccommodated, the control unit 26 identifies that no paper isaccommodated in the multifunction device (B). In this case, the controlunit 26 switches the display of the conversation partner who isresponding from the display of the general-purpose automatic response AIto the display of the multifunction device (B) in which the state whereno paper is accommodated is reflected. In the example illustrated inFIG. 30, the control unit 26 displays a device image 264 associated withthe multifunction device (B) in which the state is reflected, in thedisplay area 56 a as an image associated with the conversation partnerwho is responding. The device image 264 is an image representing themultifunction device (B) and indicating the state where no paper isaccommodated in the multifunction device (B). Of course, the controlunit 26 may output character information or voice information indicatinga state where no paper is accommodated in the multifunction device (B),in place of the device image 264 or along with the device image 264.

Further, the control unit 26 notifies the user that there is no paper bydisplaying a message content 266 indicating that no paper isaccommodated in the multifunction device (B) in the display area 56 a asa message content of the multifunction device (B).

The control unit 26 acquires the status information from themultifunction device (B), for example, at predetermined time intervals.When the multifunction device (B) is replenished with paper, the controlunit 26 acquires from the multifunction device (B) status informationincluding information indicating that paper has been replenished. Inthis case, the control unit 26 displays the device image 66 associatedwith the multifunction device (B) in the normal state in the displayarea 56 a as an image associated with the conversation partner who isresponding. Further, the control unit 26 displays a message content 268indicating that paper has been replenished in the display area 56 a as amessage content of the multifunction device (B). Thereafter, as a normaloperation, the control unit 26 displays a message content 270 as acommon question such as “How can I help you?” in the display area 56 aas a message content of the multifunction device (B). The followingprocess is the same as that of the first exemplary embodiment.

As described above, according to the seventeenth exemplary embodiment,the user may visually confirm the state of the device.

As the status information indicating the state of the device, forexample, information indicating that the device is in failure,information indicating that the device is in a sleep state, informationindicating that the device is in use, information indicating that thedevice is in maintenance, information on consumables equipped in thedevice (for example, information on the remaining amount ofconsumables), and the like may be acquired. The control unit 26 performsdisplay depending on each state of the device. For example, the controlunit 26 changes the device image for each state and displays the deviceimage in the display area 56 a.

Further, the control unit 26 acquires information indicating the stateof the function (status information), and switches the display of theconversation partner who is responding from the display of thegeneral-purpose automatic response AI to the display of the function inwhich the state is reflected. As the status information indicating thestate of the function, for example, information indicating that thefunction is stopped, information indicating that the function is in asleep state, information indicating that the function is in use,information indicating that the function is being updated, informationon the expiration date of the function, and the like may be acquired.The control unit 26 performs display depending on each state of thefunction. For example, the control unit 26 changes the function imagefor each state and displays the function image in the display area 56 a.

Other Exemplary Embodiments

The combinations of objects to be linked described above are not limitedto the combinations in the above-described exemplary embodiments. Forexample, when at least two combinations among devices, functions(including functions executed by devices and functions executed bysoftware), files, and software are identified as objects to be linked,notification of linkage functions executable using the combinations maybe controlled. For example, when a device image and a file image areidentified as objects to be linked, the specifying unit 30 specifieslinkage functions executable using the device associated with the deviceimage and the file associated with the file image, and as a notificationof information on the linkage functions, the control unit 26 may displaythe information on the linkage functions on the screen 56 as a messagecontent of the automatic response AI, or may output the information onthe linkage functions as voice information. As a specific example, whena device image associated with the multifunction device (B) and a fileimage associated with a document file are transmitted to the automaticresponse AI as information on objects to be linked, the specifying unit30 specifies linkage functions executable using the multifunction device(B) and the document file (for example, a function of printing thedocument file by the multifunction device (B), a function of facsimiletransmitting the document file by the multifunction device (B), etc.).The control unit 26 controls the notification of the information on thelinkage functions. Similarly, when a function image associated withsoftware and a file image are transmitted to the automatic response AIas information on objects to be linked, the specifying unit 30 mayspecify linkage functions executable using the function associated withthe function image and the file associated with the file image, and thecontrol unit 26 may control notification of the information on thelinkage functions. As a specific example, when a function imageassociated with a document application and a file image associated witha document file are transmitted to the automatic response AI asinformation on objects to be linked, the specifying unit 30 specifieslinkage functions executable using the document application and thedocument file (for example, a function of editing or outputting thedocument file by the document application, etc.). Further, when a deviceimage, a function image, and a file image are transmitted to theautomatic response AI as information on objects to be linked, thespecifying unit 30 may specify linkage functions executable using thedevice associated with the device image, the function associated withthe function image (for example, software), and the file associated withthe file image, and the control unit 26 may control notification of theinformation on the linkage functions. As a specific example, when adevice image associated with the multifunction device (B), a functionimage associated with a document application, and a file imageassociated with a document file are transmitted to the automaticresponse AI as information on objects to be linked, the specifying unit30 specifies linkage functions executable using the multifunction device(B), the document application, and the document file (for example, afunction of editing the document file by a document application andoutputting it to the multifunction device (B), and printing andfacsimile transmitting of the document file by the multifunction device(B), etc.). The combinations in the above-described specific examplesare merely illustrative, and linkage functions executable by combiningdevices, functions, files, and software other than those described abovemay be determined. Further, the information of the device, the function,the file, and the software may be transmitted to the automatic responseAI by voice.

Further, when the above-described combination is identified as objectsto be linked, the control unit 26 switches the display of theconversation partner who is responding from the display of thegeneral-purpose automatic response AI to the display of the combination.For example, when a device and a file are identified as objects to belinked, the control unit 26 displays a device image associated with thedevice and a file image associated with the file in the display area 56a as images associated with the conversation partner who is responding.The same applies to other combinations.
